Administration Joomla! 5.x • SMTP Error Sending Email from J5 Server

Our site has a contact us form that allows a user to fill in their information and send it to us in via Gmail. We have been doing this for a very long time. Recently we started getting the following error message.

SMTP Error: Could not connect to SMTP host. Failed to connect to server

Initially I contacted our webhost, and they made some changes, and it worked for about a day. Since then, I have tried the following to get around this without success. This includes:

Double checking the Gmail account and password.
Using a different Gmail account.
Changing from Port 465 and SSL/TLS to Port 587 and STARTTLS.
Turning off 2FA.
Turning back on 2FA and using a Google App Password (including removing the spaces).
Using a different Gmail account with app password.

I considered having out host setup an email for us, but our domain is not with them but with Microsoft 365 that is not possible.

I created a log of the error but did not see anything I understood. I could post it, but it contains our URL and some customer information (they filled into the contact form).

At this point I have run out of ideas and need some help. Please be specific as I am not a developer.
