Bug report #16686

Accessing CSW interfaces using TLS fails with SSL error for some servers

When accessing CSW endpoints that are using TLS (https) requesting GetCapabilities fails for certain servers.
Error message:
[Errno 8] _ssl.c:504: EOF occurred in violation of protocol

Obviously this is due to certain features the remote server is supporting. Is there any way to fix this?

Ok, found this is an issue due to the bundled Python 2.7.5 which is not supporting TLS 1.2.
If I do replace Python with a more current version (2.7.14) the problem disappears.

Was this closed because we assume this is fixed in QGIS3 (with Python3)?

#4 Updated by Stefan Blume over 6 years ago

I closed this issue because it is not related to MetaSearch Catalogue Client, so from my point of view it can be considered to be "invalid".
Yes, I expect a solution w/ the next major and I also do not expect a fix for this on 2.x branch, so I didn't create a new issue for QGIS itself.
