We have a specific application failing to connect to the MTA.
In mail.log_current we see:
17.xx.xxx.x SMTP STARTTLS failed, aborting connection: Peer reports it experienced an internal error. (-12188)
On the client side:
"Cannot connect with transport: Cannot connect to SMTP server: mail.abc.com, as: cstation, message: Could not convert socket to TLS, cause: java.lang.RuntimeException: Could not generate DH key pair"
Tried modifying config parameter to:
instance.base.ssladjustciphersuites = +WEAK+DES
but this made no difference.
Upgraded MTA system from version 188.8.131.52 to 184.108.40.206.
Set tlsminversion TLS1.0
