For me it usually works to change server/country if a video is not working. Sometimes it takes 2-3 tries, and it is annoying.

Hi OP, I am in a similar situation as you were so I wonder which solution you chose at the end and if you are happy with it?

I recently migrated from Github to Codeberg and it was super easy. You can also backup your code automatically from Codeberg to Github just in case.
