You have lost connection solution | disable IPV6

I was having this issue and didn't see any solution out there that worked. 

What worked for me is disabling IPV6.

I'm windows 11 but it should work for others(hopefully)

Go to Settings -> Network & Internet -> Advanced network settings -> (either a WIFI or ethernet adapter, whatever you're using)

Click the down arrow to drop down -> More adapter options -> edit 

Just Uncheck where it says: "Internet Protocol Version 6 (TCP/IPV6)"
