Antivirus block malware when launch War Thunder Steam?

When opening War Thunder Steam PC version, Every time last 3 days, Bitdefender warns of a block:

Suspicious connection blocked now. Resource: Online Threat Detection. msedge.exe attempted to establish a connection to cdn.simulationdaily.com using a non-matching certificate. We blocked the connection to keep your data safe because the certificate used was issued to a different address than the target address.

When trying to visit this domain manually:
This server could not prove that it is cdn.simulationdaily.com. The security certificate is from *.storage.googleapis.com. This may be caused by an incorrect configuration or by an attacker intercepting your connection.

Go to SITE (not secure)

My guess: Some internal War Thunder advertisement uses the domain “https://cdn.simulationdaily.com/”, but this domain has an invalid certificate configured.
