after upgrade to TSW2_R_00.01.02.2 I lost SSH access to TSW202.
Upgrade was done with setings preservation.
SSH client is able start autnetication, but then it will fail.
I was able to use root@switchip with admin password before upgrade.
I noticed “Enable SSH access” in admin account setup, so I turned it on.
Neither root@switchip or admin@switchip works.
I tried to change password through WebUI several times.
There are not any log entries regarding SSH in webUI with exception of previous sucessfull SSH login with previous firmware version like:
Password auth succeeded for root from 192.168.8.65:37496
Can you please advise what kind of configuration you had before the firmware upgrade? This could be a software migration issue; therefore, you might need to reset the switch to its default settings as a last resort: TSW202 Maintenance - Teltonika Networks Wiki
Please note, if you have the device locally accessible, and the configuration is not complicated, you could reset the switch to factory setting, this might be the easiest way to fix the issue.
Could you please download the troubleshoot file and forward it to me? To download the troubleshoot file please navigate to System → Maintenance-> Troubleshoot → Download Troubleshoot
