NetXMS Support Forum

I've been installed NetXMS 2.0 on Ubuntu 16.04, the whole process was a new installation. Everything was working fine until I login into web console showing me: ' Server uses incompatible version of communication protocol ', also I ' nxdbmgr check '  which was all passed and ran ' netxmsd -D 9 ' tried to ran server in foreground which was working normal, but with web console never allow me login into successfully.

Anyone can help with this problem:' Server uses incompatible version of communication protocol '

Thank you!

Most likely your server version is older than your WebUI version. Please update your server and WebUI to the latest stable version (2.0.8 ) from https://netxms.org/download/

Check the version of the Web UI as shown in the bottom right corner of the logon screen and compare it with the NetXMS server version you are running.
If they do not match, you will see this error.
