@TenPatrol made this post about the Windows Host File, and how it could cause server connectivity problems. You should check yours and if it’s got some weird entries, reset it back to default.
A link to Microsoft’s instructions for resetting the Host File to Windows default is in the post I linked to in the above paragraph.
I looked at the Host file on my Win11 sim computer and it looks exactly like the default host file (also shown in the Microsoft “How-To” link.)
