@argylega have you restarted the Mariadb and apache services, or the whole server?
I also assume you mean you can’t login to the website. Is there anything in the apache error log?
@mttpr1 Thanks, that was basically it - apparently the Surface dock itself has a MAC address, so that’s what was causing the issue. No way around it really, but at least I know what the problem was. Thanks for pointing me in the right direction!
