Could not Connect to server - additional log files to examine

[makramalla]

Hello,

I am trying to connect to a netconf server, however I am not able to connect properly.

It seems like the tool just stops reading the modules at some point, although I am using standard modules which usually is parsed with no issue.

This is the output from the /var/log/messages file for your reference:

On the GUI itself, I get the following error:

It is worth mentioning that I am able to connect with no issue to other netconf servers in the same network, which is why I am mainly asking whether there are any other log files other than /var/log/messages that I can examine to try to resolve this issue.

Thank you again for your continuous help.
