Screenshot of the error:
This error may occur with Two-Factor Authentication after accepting the token code or after entering the answer to a security question. The time limit reaches 0 while authenticating, triggering this error.
To fix it, increase the remote authentication timer with the following CLI commands:
# config system global set remoteauthtimeout 60 end
'60' is a recommended value which will give 120 seconds for the authentication process to complete. The default is 5. Use any desired and suitable value. |
