Might as well try phone tethering using mobile data to your desktop, if it can connect to rainbet then perhaps its your router that has issue.
I tried this, and I can now access Rainbet on my desktop computer. It's so weird, because I'm still using the same ISP.
My phone and my desktop computer were both connected to the same router. My computer was connected via a LAN cable, and my phone was connected via Wi-Fi.
Now, I've disconnected the LAN cable. My phone is still connected to the same router and my computer is connected to the internet through my mobile tethering.
So weird. I connect to the same ISP in two different ways. One makes Rainbet think I'm in Germany, while the other makes it recognize my correct region.
Im assuming you tried restarting your desktop already?
Yes, I've had the same issue for the past 2-3 days, and I've restarted my computer several times.
Another thing I can recommend would be the cave man fix which might works, try turning on and off your router few times. It usually will reset back to the original location
This couldn't be the issue. I checked my IP address through several different IP checker tools, and they all reported my correct region.
It's only Rainbet that recognizes my region as Germany when I connect my desktop computer directly to my router.
