Mismatch of SSL version or Cipher

Questions
#1

Hello
I’m having some trouble when setting up the n8n server. I did the entire docker-compose installation with traefik from the documentation(Server Setup | Docs). Everything is running but when I try to access the server via my domain I get an error saying: ERR_SSL_VERSION_OR_CIPHER_MISMATCH from my browser (google chrome). I tired installing n8n on a server in the google cloud and on my own raspberry pi but I always get mismatch error in the end.

If you know the solution to this I would highly appreciate it if you could help me with this. Or maybe some debugging techniques.

Thanks in advance!

Hey @Cedi,

Have you checked the logs for Traefik? I suspect it has failed to get the Let’s Encrypt certificate or an environment variable is wrong. The logs should provide a hint, maybe it is the email address?
