There is a problem with your SMTP setup!

I’m trying to invite users to my self-hosted n8n instance but I get the ’ There is a problem with your SMTP setup!’ error. I’m using sendinblue SMTP for sending the emails, using their official guide

Error message

There is a problem with your SMTP setup! 139678397106560:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:…/deps/openssl/openssl/ssl/record/ssl3_record.c:331:

What I tried

  1. Using google SMTP instead of sendinblue
  2. Using ‘/signup?inviterId=ID_OF_INVITING_USER&inviteeId=ID_OF_INVITED_USER’ method.

docker-compose.yml

  - N8N_EMAIL_MODE=smtp
  - N8N_SMTP_HOST=${SMTP_HOST}
  - N8N_SMTP_PORT=587
  - N8N_SMTP_USER=${SMTP_USER}
  - N8N_SMTP_PASS=${SMTP_PASSWORD}
  - N8N_SMTP_SENDER=${SMTP_SENDER}
  - N8N_SMTP_SSL=true

Environment variables in the .env are based on the credentials I found in the SMTP & API on Sendinblue

I just want to invite users, I don’t mind how.

Thank you in advance

Hi @wlaj
Set ssl to false.

It is a bit confusing sometimes but the port you are using is a TLS port which is a bit different than normal ssl, so it has to be on false in most cases

Crazy fast reply, can’t believe I didn’t think about that, thanks!
