Cannot Set Up Samsung Default Email and Add CenturyLink.net Account

Samsung Galaxy S9 phone Until recently I could send/receive emails on my phone with the Samsung default email app with an email address at centurylink.net. I had a problem with my centurylink.net email and a Samsung support person told me to go into the Mail app and Delete Data, and then I would just have to log in again. However, I have not been able to Set Up Email and Add Account. I get “Couldn’t verify account The username or password is incorrect or POP3/IMAP access isn’t turned on for this account. Check your email account setting on the web, then try again.” I have confirmed that I have entered my full email address and password correctly (Show password). I can log onto centurylink.net with them on my phone with a browser. Samsung support says talk to my email provider and Centurylink support says to talk to Samsung. I have gone through this loop 3 times, but still have the problem. I have also searched online for a solution, but found none. I am using these parameters, as Centurylink says to use at https://www.centurylink.com/home/help/internet/email/setup-email-on-android-device.html Domains centurylink.net Incoming Server (choose one) POP: pop.centurylink.net, Port: 995, Security: SSL Outgoing Server SMTP: smtp.centurylink.net, Port 587 TLS Username Full Email Address
