I don't think it matters. I think you should just reply with the new ip/port to the original application, so it can be updated. Not sure if this has changed though, so someone from the Global team can correct me.
The Global Api has had a lot of stability issues lately, so its most likely due to that you have seen issues with !gc. You can follow the #alerts channel in https://discord.gg/csgokz to see the status.
