NetXMS Support Forum

Just upgraded to NetXMS version 3.2.400 from the Debian buster repository and also updated the web console with the following release:
https://www.netxms.org/download/releases/3.2/nxmc-3.2.400.war

Unfortunately, have been unable to connect to the NetXMS service via the web console; it gives the following error:
Server uses incompatible version of communication protocol (server=[52, 4, 1, 1, 1, 27, 1, 2] client=[52, 3, 1, 1, 1, 26, 1, 2])

Please assist.

First of all, please try to undeploy and deploy again the web console.

Tried, several times. No effect. Tried older versions as well - didn't help.

Just checked that exact file - works correctly with server 3.2.400. When you are on login screen, what version is displayed in bottom right corner?

Best regards,
Victor

3.1.241 is displayed.
This pointed me towards the culprit: /var/cache/tomcat9 had the old cached information, which I now purged manually, and everything works now. Never had this kind of issue when upgrading previously.
Thank you.
