Hi, i'm running ssh tectia server There are 4 user accounts using key authentication. 2 accounts works well. The other 2 newly created accounts will fail around once a week with the following error msg in eventview. The connection error can always be resolved with a restart of the ssh server. Appreciate any help.. By the way, i've tried increasing the logging to 40, under troubleshooting options, but the log file is empty =(

"411 Logon failure, Username: ..., Reason: Key Exchange failed, Src IP:xxx, Dst IFace: listener, DstIP:xxx, Src Port:xxx, Dst Port:22, 'com.jcraft.jsch.JSchException: Auth fail, Remote Disconnect", Session Id:xxxxxxxxxxxxxxxxxxxxxxxxx

Hi Kaul,

This sounds familiar. Although 5.3.3 is already quite old and not supported anymore. There is a very good chance this has been fixed in more recent versions of Tectia Server. The most recent one as of this writing is 6.2.

You can find more info on how to start the server in troubleshooting mode here
