Servers are Unavailable (invalid server region)

Around 2 - 4 weeks ago MCC custom browser and MCC matchmaking wouldn’t load for me.
When I went on social matchmaking it would just kick me back into the game/mode selection without any prompts coming up to tell me what’s wrong

For custom browser it just never stops loading and none of the servers show up. Sometimes a prompt might show up saying that my server regions are invalid and I need to reset to defaults, I reset to default yet it doesn’t do anything, not just that I go to the server region settings and they keep loading and on the times they do show the regions, it says the ping is unavailable.

Can anyone help me here? I’ve verified folders, I’ve reinstalled my game, restarted my PC and nothing is working

Also I copy and pasted this post on Reddit and within 20 minutes of making it. It got taken down by Moderators for no apparent reason

“blah blah we take down posts to make communities safe blah blah”

like what the hell


I came in here to say I have the exact same problem. In fact, I was in the middle of typing out the reply when I figured out the solution.

Did you mess with the hosts file to improve your ping in Infinite? Mine started working again when I restored the hosts file to its original state.

100% what MetaRidley said, after reverting back to its original state the problem was fixed.

Yup! I had the excact same issue due to changing the adding servers in the host file for lower ping on halo infinite. Guess I will remove it anytime i play mcc.
