Survius servers were facing some difficulties earlier and are supposed to be fixed. If they aren’t for you, don’t panic.
Just try flushing your DNS by going into CMD and typing out “ipconfig /flushdns” without quotes.
If it doesn’t work, just restart your router,
If it still doesn’t work, just wait till tomorrow. Sometimes DNS cache clears may take upto 24 hours depending on your ISP or Router configs. Just be patient, and enjoy the game 😀
