Add a rewrite URL rule to your webserver config, i.e. for Apache 
something like:

RewriteRule ^/wms/(.+)$ 
/qgis/qgis_mapserv.fcgi?map=/path/to/project/basedir/$1.qgs [QSA,PT]

I've seen this with certain QGIS server versions on Windows, that as 
soon as the print template contains a Label, it errors out. See 
https://issues.qgis.org/issues/15440.

Please run the application in development mode (i.e. yarn start), open 
the browser console (typically F12), and in the javascript console, you 
should get a traceback. That should give a good indication of where an 
error occurred.

Your config.json contains a proxy service URL, but you aren't running 
one (at least, not on localhost:5000). Either run a proxy service, or 
clear the setting in config.json. Consult the documentation on why and 
when a proxy service is needed.

This is a broader problem that the qgis server / assets are not 
reachable from those other systems. You'll need to double check this, it 
is not a QWC2 specific issue.
