I tried to login but failed, then I reloaded the page and get that error
Discussion
Do you see any errors in the Javascript Console when you try to login? What happens when you try to login?

That error is something else. nostrich.gg is refusing NostrGram's request to load the nip05 verification. That wouldn't affect your ability to login.
Do this. Create a throw-away account and try to login with that and see if it works. If it doesn't, send me the private key of the throw-away account and let me know what browser and browser extension you're using to login and I'll try to duplicate the issue.
