Seems like my BOSH issue was encountered previously here:

> I can’t find any hint how to fix this BOSH problem. Is here anyone who has mod\_bosh in ejabberd on port 5443 and tls: true and jsxc still working?! Even if I put tls on false - then I lose http\_upload. https:\:5443/bosh leads correctly to the test-page of mod\_bosh, so the bosh server obviously works. But if I start jsxc and type in the domain field the check outputs a failure BOSH server NOT reachable or misconfigured. 502 Proxy Error Any hint welcome!
From the discussion, it looks like it’s a matter of JSXC’s version, but it doesn’t explain why I can’t reach the server from other clients…
In my situation:
> [https://mydomain.freedombox.rocks:5443/bosh](https://mydomain.freedombox.rocks:5443/bosh) does not lead anywhere.
> The internal server issue persists when I try to connect via other clients.
Is there anything that I can do to connect to the ejabberd server ?
