Known Issue details for Application Connector v1.0.x

662641 : AVR does not show pool member statistics with Application Connector nodes

Component: Application Connector

Symptoms:
When looking at AVR charts, pool members served by Application Connector Service Center do not appear.

Conditions:
This occurs when AVR + Application Connector is provisioned, and you are looking at AVR statistics.

Impact:
Pool member statistics are not available, and the pool members are not displayed.


659625 : Manually adding a node to a second proxy will mark the node forced offline

Component: Application Connector

Symptoms:
When manually adding nodes to two Application Connector Proxy instances, the initial state after adding is Disabled. On the BIG-IP this makes the node Forced Offline.

This also applies when you manually add identical nodes to a second Application Connector Proxy instance, the initial node state on that proxy is Disabled. If the node was enabled from the other proxy, it will become disabled.

Conditions:
Two Application Connector Proxy instances connected to a BIG-IP from the same VPC and you are manually adding identical nodes for redundancy.

Impact:
When the node is added on the second proxy, it will mark the node as Forced Offline until you enable it from either proxy.

Workaround:
This does not occur if you are creating nodes using the REST API, because they can be set to Enabled in the same API call.


656795-1 : Source address persistence does not work

Component: Application Connector

Symptoms:
When you configure source address persistence for an Application Connector Virtual Server, persistence does not work.

Conditions:
This occurs with Application Connector on the Application Virtual Servers.

Impact:
Source address persistence does not work. The only persistence method that works in this version is Cookie Persistence, and it requires an iRule in order to work properly.


653066-1 : Pool member status is Red on the standby, long failover times

Component: Application Connector

Symptoms:
When Application Connector is deployed with health monitors, the pool members will appear Red on the standby. When the active traffic-group fails over, it can take several seconds (up to 20) for the pool members to become green.

Conditions:
This occurs when Application Connector Service Center is deployed in a HA environment. The long failover times can occur with or without health monitors.

Impact:
The Application Connector Service Center is not running on the standby traffic-group, so health checks will not be successful on the standby device until it has started and connected to the Proxies. This can cause the failover to take up to 20 seconds to complete.


651625 : Application Connector Service Center requires HTTPS on the Proxy Virtual Server

Component: Application Connector

Symptoms:
When you associate the Service Center's "Proxy Virtual Server" to a Virtual Server configured to listen on HTTP, the connection from the Application Connector Proxy to the Service Center fails.

Conditions:
The Virtual Server associated with the Proxy Virtual Server is not an HTTPS virtual server, or there is no clientssl profile.

Impact:
Connections from the proxy will fail with Error 403: Failed to establish connection to WebSocket Server

Workaround:
Make sure the Proxy Virtual Server is listening on port 443 and has a clientssl profile associated with it.


651108-1 : Only Round Robin load balancing is supported with Application Connector nodes

Component: Application Connector

Symptoms:
When you add cloud nodes provided by Application Connector to a pool using any load balancing algorithm other than Round Robin, load balancing fails and all traffic is directed to the first pool member in the list.

This may also either prevent traffic from going to the cloud nodes , or force 100% of the traffic to the cloud nodes, if the cloud pool members co-exist with local pool members in the pool.

Conditions:
Cloud nodes provided by Application Connector exist in a pool, and the pool's load balancing method is not Round Robin.

Impact:
Since cloud pool members from Application Connector have no pool member statistics, all of the statistical load balancing methods will fail because the stats will read 0. For example if the load balancing method is Least Connections, the first pool member will always have 0 connections associated with it so all traffic will go to the first pool member.

Workaround:
Always use Round Robin load balancing with cloud nodes provided by Application Connector.


650368-1 : No persistence records for traffic going through Application Connector

Component: Application Connector

Symptoms:
When you run tmsh show ltm persistence persist-records, there are no records even though cookie persistence is enabled and working.

Conditions:
This occurs if persistence is configured for the virtual server, such as Cookie Persistence, and you want to see the persistence records.

Impact:
LTM will show no persistence records, and there is no way to see persistence records from LTM. All traffic is going through an iRule and bypassing the persistence tracking in LTM.


649410-1 : You can only run one instance of the Application Connector Service Center

Component: Application Connector

Symptoms:
When you try to launch a second instance of the Application Connector Service Center, the second instance is added but it does not work. The status shows as red and when you click into it, you see the configuration of the first service center.

Conditions:
This occurs when attempting to create more than one Application Connector Service Center using the iAppsLX menu in the GUI.

Impact:
Two service centers appear in the iAppsLX menu but they both are the same service center. All additional service centers appear as red.

Workaround:
Only configure a single Application Connector Service Center per BIG-IP device.


647184 : Application Connector Service Center RPM must be installed on all devices in a device group before configuring it

Component: Application Connector

Symptoms:
After installing Application Connector Service Center on one device in a sync group, after syncing it appears to be installed on the other devices when you look at iApps :: Package Management LX, but you cannot configure it on the other devices.

Conditions:
This occurs when installing the Application Connector Service Center RPM only on one device.

Impact:
The contents of the RPM are not synced to the other devices, and any attempt to configure the Application Connector Service Center on the other devices will fail.

Workaround:
You will need to install the RPM on all of the devices in the sync group before configuring it. This only applies to the initial installation. The configuration only needs to be configured on one device and synced.


647157-1 : Application Connector can be assigned to a traffic group different from the virtual servers it serves

Component: Application Connector

Symptoms:
In a HA configuration, if Application Connector Service Center's virtual IP is assigned to a different traffic group than the virtual servers it is serving, an outage could occur if the virtuals are active on a different device

Conditions:
This can occur if Application Connector Service Center is configured on one traffic group, while the virtual servers it is tunneling exist on a traffic group. If the application virtusl servers are active on a device where the Service Center is in standby mode, the virtual servers will be unable to pass traffic.

Impact:
When this occurs, a traffic outage will occur.

Workaround:
When configuring Application Connector Service Center, make sure that the Proxy Virtual Server is in the same traffic group as all of the Application Virtual Servers.


646863 : Application Connector Proxy does not redirect HTTP to HTTPS

Component: Application Connector

Symptoms:
When you log into the Application Connector Proxy using a web browser, you must specify https as the protocol or the page will not load, there is no redirect.

Conditions:
Attempting to log into the Application Connector Proxy using http and not https

Impact:
Unable to load the page, in the browser it looks like the proxy is down but it is closing the connection.

Workaround:
Switch to https and the page should load as long as the proxy is running.


646859-1 : Online help missing in Application Connector Proxy

Component: Application Connector

Symptoms:
When you click the online Help button in Application Connector Proxy, there is no help content.

Conditions:
This occurs when looking at the online help.

Impact:
There is currently no online help available for Application Connector Proxy


646852-1 : Adding a node to the Application Connector proxy causes it to re-sort while entering data

Component: Application Connector

Symptoms:
While entering a new node to the Application Connector Proxy, the row you were entering data on suddenly moves to a different part of the list

Conditions:
This can occur when the column you are sorting on gets new data entered into it. Sorting is immediate and the row is moved to where it would be if the row were entered completely.

Impact:
The row you were entering data on will suddenly change. Also if the data you entered would cause the record to be sorted to the top of the list, the sort still happens and you lose input focus on the edit box.

This has no impact to traffic, you just need to click into the fields to finish inputting data for the node.


646849-1 : If the Application Connector Proxy loses connection to the BIG-IP, the GUI does not display the configuration

Component: Application Connector

Symptoms:
If an Application Connector Proxy is connected and authorized with a BIG-IP, a record will show in the "BIG-IPs" table showing that it is connected; however, if the proxy loses connection to the BIG-IP for any reason (network issue, dns issue, BIG-IP restart or reboot), the GUI will stop displaying the BIG-IP.

Conditions:
This will occur if the proxy loses connection to the BIG-IP for any reason.

Impact:
If you look at the proxy GUI it will appear that there are no BIG-IPs configured, nor any nodes, and that you need to configure everything from scratch.

Workaround:
If the BIG-IP was simply rebooting, you may be able to re-add the BIG-IP connection to the proxy, and BIG-IP will automatically re-authorize the proxy. Once this occurs, any pre-existing nodes that were configured on the proxy when the BIG-IP is reconnected.
