Will look into it.
Thanks for your request!

It works for me:
Please make sure you uncheck "Valid name" in "Certificate requirements".

[seba76]

Thanks for the tip, that worked. However it looks like I found two bugs.

• Account settings, port shows 5222 even when I enter 5223

• if I click info
  apps crashes.

Also do you get roster?

[COM8]

Yes looks like a UI related bug.
Could you please upload your logs ("Settings" -> "Misc" -> "Export logs" and upload the zip file).
Please make sure: If you have changed the log level to debug and tried to connected the logs will contain your password, so delete it before uploading your logs.

Thanks!

Here is a log file, I've obfuscated emails and pass.

I clicked close by accident so reopening it again.

Thanks! Spotted two problems:

Failed to load OMEMO prekeys

I really have to find an other way to store all the stuff locally sqlite-net-pcl is by far not well enough maintained and so far to buggy...

Requesting the roster fails with bad-request (If set, the 'from' attribute must be set to the user's full JID.)

UWPX sends the following valid roster query:

<iq type="get" id="9f039e98-bacd-4eb3-8c2f-389fe9a23943" to="[email protected]" from="[email protected]/YYYYYYY">
  <query xmlns="jabber:iq:roster" />
</iq> 

Looks like it want's from="[email protected]/YYYYYYY" to be from="[email protected]".

Is gtalk, really a thing to work on now? I would ask for a PR

[COM8]

I'm not working on this right now since gtalk is more or less dead.
