Flint router no longer working

Hi everyone! I use flint router as a server at home in the US while I travel with my travel router globally, so I divert traffic through my home server. I also have wireguard app on my phone where I have a configuration that I used to connect to my home modem. Well, all of a sudden one day neither my wireguard phone nor the config I have on my travel router is working. The internet in the US is on and functional and my server router is on and I can see I'm connected to it via my travel router, but the light is orange to get no internet. any idea what's going on? I'm in Thailand at the moment. Thank you!
