Owntracks HTTP help

Hi,
I’m trying to configure own tracks via http and have an error at own track configuration page.
I use parameters:
http:/xxx.xxx.xxx.xxx:8123/api/owntracks/user/phone
and I have status:
idle The operation couldn’t be completed
network error

Any, help please?

I think you have to use HTTPS, see here for details on configuring that.
