latest version has broken ssh key authentication

I have had the same key setup for years now and in last version it working.
I updated to 2026.2.7.0 64-bit (PreJIT) this morning and now all connection that used to work with this key fail.
If I use user/pass it works. Using same key in WinSCP (same server) still works.

What was changed?


I am connecting to server 1 (RHEL) via ssh as usera + key. This is the jump host setup in the ssh gateway tab.
I am then connecting to server 2 (RHEL) via ssh as userb + same key.
This has worked for years.

Checking logs on server 2 and it seems to be failing because it is passing usera to server 2 instead of userb

this was setup as inherited which used to work but is not now.
I switch connection to use username/pass and hardcoded. but it is still passing the usera to server 2 instead of userb.
