Transport-XMPP failing to start

olivierlambert

Thanks, understood

Just to be clear it's the Transport-XMPP plugin itself giving the error when I try to turn it back on.

Backup-Reports is still on and thinks it's working.

Seems like the problem was introduced here. Don't you need so call this._client.start in order to initiate the connection?

@Danp Thanks for the pointer, investigating

Me either, but this update appears to at least resolve the issue of Cannot read properties of undefined (reading 'socket') when starting xo-server.

julien-f

@techiem2 Do you have the ability to test?

techiem2

@julien-f If you can give me instructions on how to update the plugin with the updated version, i'll give it a shot!

julien-f

@techiem2 Sorry, I missed your message.

Are you using an official XOA or XO built from the sources?

@julien-f
From Source using ronivay's script:

@techiem2 In this case, I cannot tell you how to update a specific plugin or use a specific branch, you can ask for the script maintainer's help or I'll merge the PR without further tests

julien-f

The fix has been merged in master, let me know if there are more issues.

Sorry, been a bit busy.
I'll update this weekend and see if the new version pulls in.
Thanks!

Ok, so it doesn't fail with the socket error, but now it's saying unable to verify the first certificate:
Not sure if this is a plugin issue or something on my end, but normal clients connect fine.
I'm using Prosody with a Letsencrypt cert.

@techiem2 Are you sure your server's certificate is correctly configured?

Is it self-signed?

techiem2

@julien-f As far as I can tell. It's a standard Let's Encrypt cert and it works with normal clients.

julien-f

@techiem2 If you can provide me access to your server and your configuration, I might be able to investigate and maybe come up with a fix.

techiem2

@julien-f Thanks!
Just got you setup and DM'd.
Let me know if you need anything else to poke around on.

julien-f

If other people get the UNABLE_TO_VERIFY_LEAF_SIGNATURE error, check that your XMPP server provides the correct certificate chain.

You can use OpenSSL for this:

$ openssl s_client -connect $domain:$port -starttls xmpp -showcerts </dev/null
CONNECTED(00000003)
depth=0 CN = $domain
verify error:num=20:unable to get local issuer certificate
verify return:1
depth=0 CN = $domain
verify error:num=21:unable to verify the first certificate
verify return:1
depth=0 CN = $domain
verify return:1
