[Lizmap] Printing complex base maps

[Paolo Cavallini]

Hi all,
I have a project with several complex and slow base maps (two external
WMS anfd one local vector). Printing works fine, except for the fact
that the base maps are not printed, even at low resolution (100 DPI).
Nothing shown in the log, except for a probably not relevant:
2020-03-02 08:13:26	10.10.72.5	warning	2020-03-02 08:13:26	[2]
file_get_contents(http://127.0.0.1/cgi-bin/qgis_mapserv.fcgi?service=WMS&request=GetCapabilitiesAtlas&map=%2Fhome%2Flizmap%2Fgeoportale%2FTest%2Eqgs):
failed to open stream: HTTP request failed! HTTP/1.1 501 Not Implemented

Is there any suggestion? Can increasing the timeout defaults solve the
issue? Unfortunately the project is not public, so I cannot let you try.
Thanks in advance.
Cheers.
