[Qgis-user] QGIS+Proxy+HTTPS

[Pasquale Di Donato]

Dear list,

I'm trying to access some GeoJSON resources on a HTTPS Server (e.g.
https://d2ad6b4ur7yvpq.cloudfront.net/naturalearth-3.3.0/ne_50m_populated_places.geojson):
using QGIS 2.14 and/or 2.8.1 on Windows 7 Enterprise 64 bit.

When connecting outside my work network (e.g. via a Wi-Fi connection) I can
get the resources without any problem.
When connecting with my work network (via a proxy) the connection does not
work (Failed connect to ...)

Any idea?

Thanks

Pasquale

Just FYI, a couple of months ago I had the same issue with password secured
GeoJSON files over https and under proxy.
The access to the GeoJSON files worked without any problem without the
proxy.
Under the proxy I had to set the environment variable as said in a previous
email.

Hi Phil,

if you are under a proxy you have to set a GDAL variable:

Settings --> Options --> System --> Environment --> Add a variable
GDAL_HTTPS_PROXY and put your proxy:port in "Value"

Hope helps,

Pasquale

Re: [Qgis-user] WMS via https - "SSL handshake failed"

[Pasquale Di Donato]

Hi John,

I can access your service too. Using QGIS 2.14.8.
Maybe you have an issue with a proxy?

 Hello All,

 I’m trying to use a WMS service over https and get the following
 error when trying to connect:

 Failed to download capabilities:
 Download of capabilities failed: SSL handshake failed

 The URL works fine in a browser though.  I’m guessing that QGIS and
 the server are not able to agree on a cipher suite.  Can anyone tell
 me what ciphers QGIS supports or any way to get more insight into the
 underlying problem?

 QGIS is version 2.18.2.

 Thanks!
