Apple Mail not recognizing "other" email account (from GoDaddy email)

I bought a new MacBook Pro running 10.15.7, set up Mail to run my GoDaddy email, all was working fine until I found out it was set up as IMAP which meant my storage limit (from GoDaddy's server) was reached within days

So, I attempted to switch to POP (which lets you select option to delete messages from server after retrieval) as my prior computer has the GoDaddy email set up as POP and works flawlessly running Mac OS 10.15.4.

After switching to POP on my new computer I got the message saying it doesn't recognize my GoDaddy login (says can't verify username and/or password).

Then, I tried switching it back to IMAP and now it's not recognizing my GoDaddy email there either.

Is there a known issue with 10.15.7, and/or why is this only happening on my new laptop and not on my old one?
