Issue Cannot reinstall Plesk using --web-interface due to hsts

New Pleskian
Server operating system version
Ubuntu 24.04 LTS
Plesk version and microupdate number
18.0.78
I recently had an issue with an update that messed a few things up, one of them being Plesk which became no longer accessible. I am trying to reinstall Plesk using the ./plesk-installer --web-interface command, but when I attempt to access the web page, it will not allow me, stating that hsts is active.

I am trying to determine where this is set on the server so that I can disable it. Server is Ubuntu 24.04

I searched through the Apache and Nginx files for 'Strict-Transport-Security' and I found the entries attached to the half dozen websites on this server, but resetting those has no effect.

Before installing, I can do a check on Chrome to Query HSTS/PKP domain and it comes up with nothing found, but as soon as I run the installer it keeps coming back from somewhere.

Can anyone point me in the direction of where I might locate this so I can continue?
