I've been having trouble opening any Excel or Word files in my browser from OneDrive, team groups, or directly through Teams. They only seem to work when I use the desktop apps. Has anyone else experienced this issue? Also, I need to mention that I'm working with GCC. I found out that Microsoft added a new domain that my proxy was blocking, which might be the cause of the problem.

It looks like the problem isn't with Excel or Word. It's more about your environment not syncing with recent changes Microsoft made. They added a new domain that the proxy is blocking, and that's why your browser apps are failing. The desktop apps are functioning fine because they don't rely on that route. You just need to update your proxy settings and allow that new domain to fix the issue.
Everything seems fine on my end, but I'm not on GCC. Have you checked if the issue is related to your network settings? It sounds like Microsoft introduced a new domain that might be blocked by your proxy, which can prevent the online versions from working properly.
What steps should I take to allow that domain? I'm not very tech-savvy!
