Hello,

I am running Traefik 1.7 inside a docker enviorment.  
The issue is that i would like to use 2 domains [test.example.com](http://test.example.com) and [test.example2.com](http://test.example2.com) to forward to docker hosts.  
It does not wan't to start working and keeps showing a 521 error from Cloudflare.  
If I remove 1 of the 2 domains everything works fine.

Thanks in advanced.
