I am running a self hosted instance in my organisation and I cannot connect to a internal SMTP server. The internal SMTP server is currently working for other applications but not for Appsmith.
Hello and welcome to our community, Justin!
Can you please let us know what Appsmith version you are on (if you are self-hosted) and what email service provider you are using?
Please send us the server logs to help us investigate the issue. You can grab the logs by running docker logs -f appsmith.
Or you could follow the steps from this guide on how to get the logs
