<![CDATA[Web UI not working - incompatible?]]>So I have NetXMS server 4.3.2 running, local client connects, no issue.  The WebUI however is not.  It reports: Server uses incompatible version of communication protocol.

The odd part, I am running 4.3.2 on both the server, local client and WebUI, yet it reports version mismatch.  I even downgraded the WebUI to v4.3.1 and I get the same error, but when I looked more closely at the error, the version doesn't seem to match up?  The error is: Server uses incompatible version of communication protocol.  (server= [60, 4, 1, 1, 1, 43, 1, 2] client= [60, 4, 1, 1, 1, 44, 1, 2]). Neither of these seem to match up with the real version... I am expecting to see 4.3.2 or 4.3.1 for the client, but seeing what I can only suspect is 4.3.1.2 (server) and 4.4.1.2 (client).

Any ideas?

Thanks for the help!

Server uses incompatible version of communication protocol (server= [60, 4, 1, 1, 1,43, 1, 2] client= [60, 4, 1, 1, 1, 44, 1, 2])

This happens with the new UI and the legacy versions.
