Issue Not able to login to plesk on lightsail - Redirects to login page.

[rsahni05]

Hi, I am unable to log in to my Plesk control panel (domain:8443). It redirects me to the login screen within seconds so unable to update any settings as mentioned in a few threads.
I haven't changed anything on the server only thing I can see is SSL seems to be expired. My website is working fine and the WordPress backend is also accessible.

Any help how can I fix this.

Thanks
