Everytime I try to sign into my Microsoft account on my Nintendo switch it gives me a code. However when I sign in on the website it doesn't do anything and I have to try over 5 times for it to work

I go into Minecraft and everything but the Microsoft loads. I click sign into Microsoft then click it again on the different page. It gives me a code. I go to the website type in the code and my password. Then I exit out of the screen and nothing changes. Then I click on it two more times but it doesn't load or give me a code. I go out of Minecraft and repeat the process several times before it finially works.
