I have tried the installation of Youtrack, Upsource and Hub to get them working together properly
First issue is that the Hub dashboard does not work. I get an error saying "Can't connect to dashboard backend".
The second issue is that when I create a project and try to add Youtrack I get the error "Error: Can not create integration.". I then went through another way and it gave me a 403 forbiden message.
The last issue is that its thrashing the CPU and hogging memory. Page loads take ages.
I have it running on a Linux box using the zip package.
