Process——

According to the test results, the console login port is set to 444.
Change the console login port back to 443 and retest to see if it works

Root cause

Software versions 11.x and later [When HTTPS requests fail authentication, redirect to the authentication page (except when using a proxy)] occupy port 444
, so you need to cancel when upgrading from 6.x to 11.x

solution

Solve by changing the console login port to another unoccupied port other than 444 (such as 443)
