VPN On, Sites won't load

When I turn on the VPN, some sites won't load. Some give an error message, others simply do nothing. If I turn off the VPN. my access to sites is unobstructed.
I see this issue in other questions, but no fixes are mentioned.
Thanks
Bill

Hello Bill,
Thank you for contacting AVG Community Support.
We are sorry to hear this. We'll check and help you out.
May I know whether you have changed the location of the VPN and checked the issue? If not, please do so and check if the issue persists.
Awaiting your response.

Thank you for updating the status, Bill.

Along with changing the server/location in your AVG Secure VPN, please enable the Mimic VPN protocol as mentioned in the below steps and check whether you can access the websites:
Open AVG Secure VPN > Menu > Settings > Protocols > Select Mimic.
Keep us updated.

After trying 3 different locations, was successful logging into one of the websites. San Francisco and Seattle fail consistently. LA seems to work for at least one site.
Thanks
Bill
