Thunderbird GMail SMTP Error

I’m trying to send emails from my gmail account via thunderbird, and I keep running into an SMTP server not found error. I’m sure I have the server configuration entered right and have OAuth2 set up. I’ve even signed out and logged in again. It used to work like a month back, but it doesn’t now.

You need to give a lot more information than this.

The name of the smtp server you are using. The full error message incl. error code and everything. thunderbird version. etc.


Here’s a screenshot of the dialog box with the error.
smtp server: smtp.gmail.com, port 465
thunderbird version: 115.14.0-1

Port 465 is for SSL. Is that what you have configured?
Can you try port 587 for TLS/STARTTLS?
Or port 25 for no encryption

It works for me with SSL/TLS and OAuth2 for identification.

Is your PC using the correct IP address? Show us the output of

dig smtp.gmail.com

The dig command is included in the package bind 9.20.0-1

Are you using a VPN or are you behind a firewall?

this worked! thank you so much!
