[qgis-qwc2] Connections to external WMS servers fails

[Sandro Mani]

Hi Roman

For development purposes, you can use browser addons which inject 
access-control-allow-origin headers to the requests (just look for CORS 
addons).

For production purposes, if it is a service under your control, either 
have it run on the same origin as QWC2 (origin meaning protocol, domain 
and port), or have the webserver serving your WMS add appropriate 
access-control-allow-origin headers. If it not a service under your 
control, you'll have to add a proxy service in between which adds these 
headers.

You'll however generally want to read up on the topic.
