Network technical issues preventing login to Microsoft account on version 1.2.11

I am unable to log in to my Microsoft account in Minecraft version 1.2.11, which seems to be caused by some network technical issues and is unrelated to the game itself.(I filled in 26.51 because there was no option for 1.2.11, and I had to enter the game code because that was the only thing I could input. I just want to play version 1.2.11.)
