Connecting to Sentinel hub with a proxy

[cnette]

I can not connect the plugin to the service due to a proxy. I try "default" proxy and "httpproxy" as settings.

It could be due to urllib to ping the website and could be resolve by QgsNetworkAcessManager like in the documentation to publish plugins : Plugins should make use of QgsNetworkAccessManager instead of using urllib2/requests/etc... which often fail to use correct proxy settings.

Hi, could you send a capture of the settings you are using? Could you tell which kind of proxy you are using?

[cnette]

Hi, This is default config and I try also this configuration HTTP or HTTPS

[Adrok24]

The proxy settings are saved and taken from a qsettings file. This file is a .config or .ini that can be found in a hidden folder in windows for example C:\Users\\AppData\Roaming\QGIS\QGIS3\profiles\default\QGIS\QGIS3.ini. Could you search for 'proxy' in this file and tell me if your configurations are stored there?
