📝 Describe your problem

Emails will not send due to the following error:

140334706751424:error:141A318A:SSL routines:tls_process_ske_dhe:dh key too small:../deps/openssl/openssl/ssl/statem/statem_clnt.c:2166:

I am sorry I just cant figure this out, any insight why this is? I have added my SMTP settings to plenty of systems, it works, never have an issue sending through SMPT. I tried my custom mail server and then my 3rd party mail sending service smtp.com.
