QRadar: IMM2 browser access is working, but remote console access is blocked

Troubleshooting


Problem

IMM2 browser access is working. However, access to "use the browser client" for remote control is blocked.  The window pop-up opens but shows that the page is blocked.

Symptom

After selecting a browser client for IMM2 remote control access as shown in the screen capture, the pop-up window appears but shows blocked.
selecting browser client

Cause

This problem is typically caused by either the IMM2 is stuck or port 3900 is blocked by the firewall.

Diagnosing The Problem

To test the firewall connections to see whether they are open, run theses commands one at a time from Windows Power Shell only:

Test-NetConnection <IMM-IP> -port 80

Test-NetConnection <IMM-IP> -port 443

Test-NetConnection <IMM-IP> -port 3900

Test-NetConnection <IMM-IP> -port 5900

If the test succeeds, "TcpTestSucceeded : True" shows as one of the lines in the results.

If the test fails, "TcpTestSucceeded : False" shows as one of the lines in the results.

Resolving The Problem

To resolve the issue, confirm "TcpTestSucceeded : True" for all 4 ports.    The IMM browser (graphical user interface) remote control access option to "use the browser client" requires 4 ports to be open for full functionality.  Ports 80, 443, 3900 and 5900 must all be open for the GUI to run and to do hardware firmware updates with remote control.  If any of the ports show "TcpTestSucceeded : False", work with your network team to ensure that all ports are open.

If all ports are open, but access still does not work.  Restart the IMM.  Also, check if any other appliances' IMM are doing the same thing.
