For the connection issues, wait a few minutes and try again, or restart, or reset your router In case of "No such host" error, please try the temporary solution posted on the forums https://royals.ms/forum/threads/no-such-host-temporary-solution.226217/
Yup, I have restarted modem and pc after adding the host info, uninstalling. once started back up reinstalled and still the same error.
I do not, I was the one who found out for windows 11 that the memory integrity needed to be turned off to run. I had exceptions and no antivirus running. I had Mapleroyals running just fine on friday.
Are you able to try running Royals on a different network such as mobile data? (just for testing to see if it would be the same error code)
You need to remove the hashtag from the line. Probably need to add it to antivirus / router now if you're no longer getting the "No host" issue
