I'm trying to add my frontier email to Mail on Mac

I'm trying to add my Frontier email to Mail on Mac but after I select the type of provider (Yahoo) and typing in my email, it doesn't ask for my password. Just takes me back to selecting a provider making it impossible to sign-in to my email. I tried 'other account' and signed in but it was just perpetually loading. I tired restarting my Mac and shutting it down but nothing changes. I don't think it's impossible to add my email since I have my Frontier email working on Mail on my iPhone and iPad. It just won't work on Mac. Any suggestions would be greatly appreciated!
