Play offline - no internet connection

For several days now, I've been getting this error: Oh no. There was a problem connecting to Microsoft services.
I have an internet connection, but the Minecraft Launcher says I can't access the network and can only play offline. I checked my Microsoft account and I am logged in normally. Some of my friends have had the same problem for several days. Please fix this error because I can't use the game I purchased. Thank you!
