Cannot login to GL-X750 web interface after update. Is the existing password too long for the new software?

Today I cannot login to the web admin interface my GL-X750 router.

When I type in my password the form field turns red after I’ve entered the 33rd character, and the “Login” button is disabled.

Has an automatic update to the firmware imposed a new 32 character limit on the password length?

If so, can I change my password over SSH? I’ve got ssh key authentication set up and it is still working.

Thank you.

Seems this is the case.

Yes you can. The password hash is in /etc/config/glconfig. Let me message you a method.
