Verify collector connection status
Perform a simple connection check
A simple check can be done by
ping. If the ping was executed successfully, a firewall can still block the communication on port "55555".
tracert command can be used to track where packets may be blocked. "External" firewalls can be identified in this way.
Test a connection to the collector with the browser
Start a browser on the ARM server and call the address of the collector with port "55555".
After a timeout, you receive an error message that the page cannot be displayed.
You will receive a message starting with ".Net..." and further containing "...expacting preamble...". This error message is generated by the ARM service.
Run the browser test in both directions. Call the collector from the ARM server and vice versa. Communication must be possible bidirectionally.
