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!
