outgoing mail servers not working

I have had this issue since last week. I cannot send an email. It's telling me the outgoing server cannot connect. Everything worked fine until 6 days ago.  I changed nothing and now I can't send an email from my iphone. I have followed all the directions from this forum that include (pasted here from a comcast employee post 2 years ago):

To set up your Xfinity (Comcast) email account on your iPhone using IMAP, you'll need to manually configure the settings within your iPhone's Mail app. First, enable Third Party Access Security in your Xfinity email settings. Then, in your iPhone's Mail app, add a new mail account, selecting "Other" and then "Add Mail Account". You'll need to enter your name, email address, and password. For the IMAP settings, use imap.comcast.net as the Host Name, your email address as the Username, and your password. For the outgoing mail server, use smtp.comcast.net as the Host Name, your email address as the Username, and your password. Finally, enable "Use SSL" for both incoming and outgoing mail servers. 
 
To configure an Xfinity (Comcast) email account for IMAP, you'll need to set specific server addresses, ports, and security settings in your email client. 
 
Incoming Mail Server (IMAP): 
  • Server Name: imap.comcast.net
  • Port: 993
  • Security: SSL/TLS
  • Authentication: Your full Comcast email address and password
Outgoing Mail Server (SMTP): 
    • Server Name: smtp.comcast.net
  • Port: 587
  • Security: STARTTLS or SSL/TLS
  • Authentication: Yes, require authentication with your full Comcast email address and password

Hello @user_4kuptk thank you for reaching out on our community forum! Are you able to send emails if you sign in directly to your comcast email on a web browser? Is it just from the mail app that the emails are not sending?

I can send/receive email from Outlook and Comcast, it's only on my phone but that's what most of us use ALL THE TIME.
