I just had a similar version mismatch problem on debian with tomcat. There is a work folder in your tomcat/work/Catalina/localhost/ with a nxmc folder that I deleted. Then rename .war to nxmc.war to have the url as  :8080/nxmc/  Do all of this with tomcat stopped ! Resolved the issue I caused by deploying different version with the same name causing the mess in in the work folder.

Regards Dawid

Other versions may or may not work - protocol version may stay the same between product versions. Usually if you got this error that means that your client is too old and you just upgrade to version matching your server version.

Best regards,
Victor

Compare that with the version of the Management Console you are running.

Depending on how many nodes/items you have in your server, it can also take several minutes between restarting the service and you being able to log in. The error in between would be a Connection Refused, not an incompatible version error.

Check the netxmsd log file and look for the "NetXMS Server started" line, which indicates that the system is ready.

If you locked yourself out with your password change, running "nxdbmgr reset-system-account" should reset the password to default.

Regarding the status from systemctl, it is showing that the NetXMS Server service is up and running.

I reinstalled the management console and get into the software but when I make changes on the server config according to the netxms videos, when I restart he netxms server I can't log back into the management console.
Here status after restarting the server:

[root@localhost ~]# systemctl  status  netxmsd.service

What do I do?
Thanks

Make sure that your NetXMS server version matches the Console. That includes minor version changes, e.g. 2.0.7 is not compatible with 2.0.8.

Cheers
