NetXMS Support Forum

Hey guys, so im currently in school doing a project where we are supposed to monitor our network and we're trying to do this with NetXMS but we won't be able to establish a Agent tunnel, were always getting the "TLS context" Error and our Agent log says it can't find such File when looking for the certificate. It won't even show any unbind tunnels etc when starting the agent. Im kinda desperate right now, because we tried every possible thing explained on this forum and we can only work on this project in school time as our server is still in school. But i'll make sure that i'll upload the log files tomorrow.

Thanks in advance and hopefully we can get this software to work!!
deadline is 13/12/2021

Here is my Agent log:

And here my Management Console

Hi,

are you sure agent can connect to the server on port 4703? Also, did you set up server certificate? Without server certificate TLS session cannot be established.

Best regards,
Victor

Yes, I have set up the required certificates and opened connections for port 4703... still no success

If you open server log at debug level 6, do you see anything there when agent is trying to connect?
