Hello Martin,
I'm sorry to hear about this. It might be because of AVG Firewall network profile. I request you to change AVG Firewall network profile to private (open AVG Internet Security > menu > settings > components > firewall > customize > network profile > change all the network public to private), please go to Firewall customize settings again > scroll down > click on system rules > enable all the system rules if it's not configured, please click OK and check if you can access all the websites with enabled AVG Internet Security.
Best regards,
Alok.

I can't access some Wordpress sites I own. However other people can access them fine. They are all hosted on Hostgator.

I get a Domain Expired page. (it's not)

This happens on my PC and my Laptop. It doesn't happen on my iPhone. 

It doesn't appear to happen to anyone else.

It happens at home and if I am using another wifi connection.
