You can add this to agent config for additional debug:
EnableSSLTrace = yes
DebugTags = ssl:8
DebugTags = tunnel:8
Does roll-back to 5.2.8 help (agent protocol is backward and forward compatible, so you can use older agent with newer server).
Hi,
please enable logging to file (by setting LogFile = some_file in netxmsd.conf), set debug level to 9 (by setting DebugLevel = 9 in netxmsd.conf), try to start service, and post log file here.
Best regards,
Victor
