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 > Troubleshooting.
  2. In the TCP dump section, enter the relevant IP Address and the Azure HA Port.
  3. Click Start.
  4. Let the capture run for a few minutes.
  5. Click Stop.
  6. Click Download.
  7. 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.

For detailed information related to TCP dump, refer to the Packet Trace Guide Technical Note.
