Sorry to hear about your error. It looks like you’re playing from Singapore, is that right?
Additionally, to help us troubleshoot, are you able to connect your PC to a mobile hotspot - to see if the error persists whilst under another connection?
Good discovery! In this case, I’d recommend reaching out to your ISP and explaining that the connection to https://bsp-sup-sd.atoma-discovery.com/darktide/status is being blocked. Your ISP should be able to resolve this for you.
