Outgoing SMTP Authentication Method Problem (functional option, require signin, not available)

Question

Hello all,
I'm trying to set up an account on my Thunderbird and I'm having a weird problem. I can receive emails on it fine but I cannot send any emails. Whenever I try to send any emails I get the error message "Syntactically invalid EHLO argument(s)".
This email address that I'm trying to add as an account on Thunderbird works perfectly fine in my Gmail Android app on my phone. The difference in the Outgoing SMTP settings are that on my (working) gmail app the Security Type = NONE and the "Require signin" box is CHECKED, whereas in Thunderbird I can set my Outgoing SMTP Security Type setting to = NONE but I do not have the option to "Require signin". All of the options that are available do not work.
Is there any solution?
Thank you!
Best, Nick
