Unfortunately you can either have a working upload OR a working jsxc webclient …
Which of both depends on your choice to set
tls = true (upload works) or false (jsxc works). The login screen informs that it cannot connect to bosh server and throws error code 520.
I don’t know much about bosh, but I understand that in the past it worked without ssl on port 5280. Maybe bosh isn’t able to use tls at all? …
