Greenlight fails to configure smtp

I have this seetings in the .env file of greenlight in my bigbluebutton server





Yes, the email works as SMTP, I use it in another service and it works fine with the correct password and the same settings

But when I run this command

docker run --rm --env-file .env bigbluebutton/greenlight:v2 bundle exec rake conf:check

The output prompts

Checking environment: Passed
Checking Connection: Passed
Checking Secret: Passed
Checking SMTP connection: Failed
Error connecting to SMTP - SSL_connect returned=1 errno=0 state=error: wrong version number

I have no idea of what is wrong with it

Thank you in advance

Well, a partner told me something that I could read correctly because of the dark blue in the vi comments. The error was that I was using this


The comment of the line above is

#   enable SMTPS: SMTP over direct TLS connection; usually port 465

So, my SMTP needed to use STARTTLS port 587 and that line was messing it all. Once commented, it all worked

You can check the following steps in this guide to configure greenlight.

Keep in mind that SMTP is disabled by default for new accounts.



I found that some people got this fixed using this code

cd /root/greenlight
docker-compose down
docker pull bigbluebutton/greenlight:v2
docker-compose up -d

But that’s not my case, everything us updated and the message prompts the same error
