Hi John,
I've captured QGIS packets to/from the WMS service, after clicking
"Connect" on QGIS (to get the capabilities document).
The print screen is available at [1].
Wireshark reports the protocol as TLSv1.2.
Regards,
Jorge

Thanks. I used wireshark to trace the session and it appears that QGIS
is attempting to make the connection with TLSv1 which I think is at
least part of the problem.
Can either of you tell me what protocol and cipher suites you’re using?
what OS you’re running on? Is there anyway to force QGIS to use a
different protocol?
Thanks!

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

Hi John,
I've added your WMS service and it works without any problem. I've
just added the url and the connect works. The capabilities are
displayed.
You can check the print screen [1] with your https WMS layer.
I'm using QGIS 2.18.2 on Ubuntu. Which OS are you using?
Regards,
Jorge Gustavo

Thanks for your reply Luigi! To be clear, the WMS service
that I’m
trying to connect to does not require a username/password but
is only
available via https. The server (https://maps.ngdc.noaa.gov
<https://maps.ngdc.noaa.gov/>) has a
valid CA certificate. I tried adding a SSL Server Configuration
(preferences -> authentication -> Manage Certificates ->
Server) and
while the entry appears to be valid, I still get the SSL
Handshake error
when trying add a WMS layer.
Any further ideas? Here’s the actual URL I’m trying to add:
https://maps.ngdc.noaa.gov/arcgis/services/gebco08_hillshade/MapServer/WMSServer?request=GetCapabilities&service=WMS
<https://maps.ngdc.noaa.gov/arcgis/services/gebco08_hillshade/MapServer/WMSServer?request=GetCapabilities&service=WMS>
Thanks again for your help!

Hi John
SSL is managed storing credentials using the QGIS
Authentication
Manager that store credentials in the same way as Firefox,
in a master
pwd crypted store in your $home/.qgis2/qgis-auth.db.
You should managed credentials using
Settings->options->authentication.
QGIS uses OpenSSL => and specifically can import different
king of
credential method (using plugins => can be expanded). De
default auth
method installed are listed in the documentation:
https://docs.qgis.org/2.14/en/docs/user_manual/auth_system/auth_overview.html
<https://docs.qgis.org/2.14/en/docs/user_manual/auth_system/auth_overview.html>
what is you auth method? can you explain the workflow you
followed to
store and use your credentials?

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!
