Server icons are not loaded

Hey, I have had the problem for a few weeks that the icons and avatars on other servers do not load. With me on the server they load. A friend of mine has the same problem. However, as soon as we join another server with a VPN, all icons and avatars load. What is the error and how can you fix it?

Excuse my english. I come from Germany and have written this text translated with Google.
