ServerDialback warning w/ self-signed certificate of remote server

Hello,

i recently discovered some ServerDialback warnings while connecting to remote servers.

I wonder if this happens because of my OF setting or is this because of the remote xmpp server?

My OF version is 3.7.1

SSL-Seetings:

  • optional: clients my use secure connection

  • optional: s2s connections my be secure

  • Accept self-signed certificates. Server dialback over TLS is now available

I am using a self signed certificate.

I know that there was a dialback problem with OF 3.7.0 but it should be fixed in 3.7.1?

Cheers!

Same thing happens to me even when using a third party certificate from Startssl, which can be considered as trustworthy.

Any ideas?

I can confirm the same.

Using StartSSL class2 Certificate

Startssl, isn’t trustworthy by default; only after adding the ca/sub-cert to the keystore.
