SSH Tunnel ----> Jumphost -----> Firewall WebUI No Longer Working Properly

[hakuntata]

I ssh into a jumphost in order to access my firewall fleet web interfaces.

I am utilizing the "local port forwarding" option in putty in order to acheive this.

I have been using this option for years without issue.

I recently upgraded 2 of my firewalls from 7.4.7 to 7.4.9. After doing so, I am able to log into the web interface of each of the two firewalls, but I am no longer able to use the GUI based CLI. I get the follwoing:

Login refused. (err=-121)

Connection lost. Press Enter to start a new session.

Is anyone also seeing this?
