[mhdshah]

I'm also facing the same issue.

[mehmetgencdal]

@vsevex any solutions?

[mehmetgencdal]

@mhdshah Which server is your XMPP based on? Metronome, openfire etc?

[mhdshah]

It's Ejabberd

[mhdshah]

I tried with SecurityContext as well.

[mehmetgencdal]

I didn't try it. It seems I'll use matrix instead of mqtt. Unfortunately

[vsevex]

Hi @mehmetgencdal, @mhdshah,

Thank you for opening an issue. Handshake exceptions are common during connection establishment in Whixp, as the Flutter framework does not provide an easy way to configure StartTLS. To resolve this, you must use DirectTLS in release mode; otherwise, the connection cannot be established. For testing purposes, you must connect to the server without establishing a TLS connection.

Additionally, there is a path exception when trying to initialize Whixp in Flutter. You can fix this issue by referring to the solution mentioned in the documentation.

[mhdshah]

@vsevex Thanks.

As you suggested, I built the app in release mode, but I still couldn't connect. Am I missing something?

[vsevex]

@mhdshah, this has nothing to do with the release version of the current application. By release, I meant the deployed version of your XMPP server with SSL certificates. The preferred port for this is typically 5223, which is referred to as the TLS-configured port. You need to activate useTLS: true when attempting to connect to this port, as it uses DirectTLS.

In your case, it is preferable to connect to the server without any SSL configuration. Therefore, try connecting to port 5222 after properly configuring your server. Ensure that the SSL configuration for port 5222 is set to false. For example, in this configuration file for the ejabberd server, you can see that the starttls_required property under the 5222 listener is set to true. In your case, you need to set this property to false to avoid a handshake exception.
