Problem opening a GeoJSON with http protocol with a script as system proxy.

[FERRATON]

What is the bug or the crash?

I use http protocol geojson to open for example:
https://www.vigicrues.gouv.fr/services/1/InfoVigiCru.geojson/
In QGIS I set proxy to default proxy
If I use a script (.pac) in the system settings, opening the Geojson fails.
It succeeds if in the systems settings I use a manual configuration.
Note that I use in the python console the instruction:
QgsNetworkAccessManager.instance().proxyFactory().queryProxy( QNetworkProxyQuery( QUrl( "https://www.vigicrues.gouv.fr/services/1/InfoVigiCru.geojson/" ) ) )[0].hostName()
which allows me to check that the proxy retrieved is the correct one when using the script (.pac).

Steps to reproduce the issue

Use a configuration where a proxy is required.
create a test.Pac file which returns the proxy directly and configure it in the Windows system settings.

I tested on QGIS 3.25 and it works.

Could you please paste me the result of these lines

# 2 means NoProxy
QgsNetworkAccessManager.instance().proxyFactory().queryProxy( QNetworkProxyQuery( QUrl( "https://www.vigicrues.gouv.fr/services/1/InfoVigiCru.geojson/" ) ) )[0].type()
QgsNetworkAccessManager.instance().proxyFactory().queryProxy( QNetworkProxyQuery( QUrl( "https://www.vigicrues.gouv.fr/services/1/InfoVigiCru.geojson/" ) ) )[0].port()
QgsNetworkAccessManager.instance().useSystemProxy()

Could you please share with me the system proxy configuration. I have this on my side

[troopa81]

Could you also post me the result of these lines

QNetworkProxyFactory.proxyForQuery( QNetworkProxyQuery( QUrl( "https://www.vigicrues.gouv.fr/services/1/InfoVigiCru.geojson/" ) ) )[0].port()
QNetworkProxyFactory.proxyForQuery( QNetworkProxyQuery( QUrl( "https://www.vigicrues.gouv.fr/services/1/InfoVigiCru.geojson/" ) ) )[0].hostName()
QNetworkProxyFactory.proxyForQuery( QNetworkProxyQuery( QUrl( "https://www.vigicrues.gouv.fr/services/1/InfoVigiCru.geojson/" ) ) )[0].type()

I was on holiday and am teleworking today and next Monday. I could do the test next Tuesday...
Kind regards

QgsNetworkAccessManager.instance().proxyFactory().queryProxy( QNetworkProxyQuery( QUrl( "https://www.vigicrues.gouv.fr/services/1/InfoVigiCru.geojson/" ) ) )[0].type()
-> 3
...Port()
-> 8080
...useSystemProxy()
->True
QNetworkProxyFactory.proxyForQuery( QNetworkProxyQuery( QUrl( "https://www.vigicrues.gouv.fr/services/1/InfoVigiCru.geojson/" ) ) )[0].port()
-> 8080
...hostName()
-> 'pfrie-std.proxy.e2.rie.gouv.fr'
...type()

strangely if we pass by a qlr file indicating the source
it works.
GeoJSON_VIGICRUES.zip

Everything returned by QgsNetworkAccessManager.instance().proxyFactory().queryProxy( QNetworkProxyQuery( QUrl( "https://www.vigicrues.gouv.fr/services/1/InfoVigiCru.geojson/" ) ) )[0] is OK : type=3=HttpProxy, port=8080, it uses system proxy!!!

but the same command with hostName returns what ? empty string ? it look very strange to me!

What returns this?

QNetworkProxyFactory.systemProxyForQuery( QNetworkProxyQuery( QUrl( "https://www.vigicrues.gouv.fr/services/1/InfoVigiCru.geojson/" ) ) )[0].port()

Same question with hostname/type/port

[FERRATON]

hostname() correctly returns 'pfrie-std.proxy.e2.rie.gouv.fr'
QNetworkProxyFactory.systemProxyForQuery( QNetworkProxyQuery( QUrl( "https://www.vigicrues.gouv.fr/services/1/InfoVigiCru.geojson/" ) ) )[0].port()
-> 8080
HostName()
-> 'pfrie-std.proxy.e2.rie.gouv.fr'
port()
->8080
Everything in the python console is correct...it is only when using the data source manager that there is a problem.
