Bitdefender just notified me twice:
Suspicious connection blocked

Function:
Online threat prevention
firefox.exe attempted to connect to suspicious-bouman.45-148-120-51.plesk.page based on a certificate mismatch. We have blocked the connection to keep your data safe, as the certificate used was issued for a different web address.
Can't find anything about this process on the web. What is it?
