I'm not sure where to put this...

Lately when I click on a game, any game, it will sometimes take me to a 404 page. The game isn't deleted, the dev isn't gone, I'm not blocked if that's a thing? It feels completely random. I have to open the game in another tab to be able to load the page. I noticed the URL is weird too when this happens but I'm not sure what that means.

Is there something I can do to fix this? Thank you!
