Hi, this is not working for me ( tested on chromium based browsers):
This server could not prove that it is sub.myhost; its security certificate is from *.myhost. This may be caused by a misconfiguration or an attacker intercepting your connection.
If I use "sub" instead of "*" it works for this specific subdomain
