Invite emails using the User Management feature are failing for some unknown reason. SMTP on my server operates on port 587 so I set N8_SMTP_SSL to false which fails with the error " Could not invite users - There is a problem with your SMTP setup! self signed certificate".
I also tested setting N8_SMTP_SSL to true which I believe is incorrect and it fails with the error “Could not invite users - There is a problem with your SMTP setup! 140467208370992:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:…/deps/openssl/openssl/ssl/record/ssl3_record.c:331:”.
I am running the n8n service through Docker on Hetzner (Ubunto 20.04). Support at my SMTP hosting provider, KnownHost, stated that it is failing due to syntax errors (see below). However I did set-up a SMTP relay at mailersend and it worked fine through their service.
Thanks in advance for any suggestions on how to fix this.
