Running a TCP dump and checking the results can also assist with troubleshooting. To do this, follow the steps below in the LoadMaster WUI:

  1. In the main menu, go to System Configuration > Logging Options > System Log Files.

  2. Click Debug Options.
  3. In the TCP dump section, enter the relevant IP Address and the Azure HA Port.
  4. Click Start.
  5. Let the capture run for a few minutes.
  6. Click Stop.
  7. Click Download.
  8. Analyse the results in a packet trace analyser tool such as Wireshark.

Checks from the partner LoadMaster should appear in the results. If nothing is shown there is a problem, for example Azure may be blocking the connection.
