Description
The following error occurs trying to open an ssl connection with certain servers using QGIS 3.22.2 or QGIS 3.16.15 from OSGeo4W v2:
Traceback (most recent call last): File "C:\OSGEO4~4\apps\Python39\lib\code.py", line 90, in runcode exec(code, self.locals) File "<input>", line 1, in <module> File "C:\OSGEO4~4\apps\Python39\lib\ssl.py", line 1342, in connect self._real_connect(addr, False) File "C:\OSGEO4~4\apps\Python39\lib\ssl.py", line 1333, in _real_connect self.do_handshake() File "C:\OSGEO4~4\apps\Python39\lib\ssl.py", line 1309, in do_handshake self._sslobj.do_handshake() ssl.SSLError: A failure in the SSL library occurred (_ssl.c:1129)
The issue doesn't occur using QGIS 3.16.15 from OSGeo4W v1.
To reproduce the issue:
import ssl import socket socketHandler = socket.socket(socket.AF_INET, socket.SOCK_STREAM) socketWraped = ssl.create_default_context().wrap_socket(socketHandler, server_hostname='prgcloud.com') socketWraped.connect(('prgcloud.com', 443))
The issue brokes the functionality of some plugins in QGIS from OSGeo4W v2: for example, qgis-cloud-plugin https://github.com/qgiscloud/qgis-cloud-plugin/issues/54 or impact-qgis-plugin https://github.com/anyways-open/impact-qgis-plugin/issues/18
Side notes:
the openssl package version installed in OSGeo4W v2 is openssl-1.1.1l-2, while
ssl.OPENSSL_VERSION
returns OpenSSL 1.1.1h 22 Sep 2020
;
the openssl package version installed in OSGeo4W v2 is openssl-1.1.1d-2 and
ssl.OPENSSL_VERSION
returns OpenSSL 1.1.1d 10 Sep 2019

I found out that copying libcrypto-1_1.dll and libssl-1_1.dll from a "normal" pyton3.9.5 install works. They have the same date (03.05.2021) than the other files in the QGIS-Python "DLLs" dir while the originals differ (also in size):
03.05.2021 18:36 3.406.016 libcrypto-1_1.dll 21.10.2021 18:35 3.439.104 libcrypto-1_1.dll.org 03.05.2021 18:36 690.368 libssl-1_1.dll 21.10.2021 18:35 687.616 libssl-1_1.dll.org
Running my code from the former comment in the QGIS-console, that works without this modification, so I think my IDE has a different path order or something like that (?)

I don't know if the two issue are related.
I've tested your code
import urllib.request response = urllib.request.urlopen('https://www.python.org/') html = response.read()
in QGIS 3.22.6 and QGIS 3.24.2 (Windows 10 64 bit - OSGeo4W) python console and I don't see any error message.
In my OSGeo4W\bin folder there are:
21/10/2021 18:35 3.439.104 libcrypto-1_1-x64.dll 21/10/2021 18:35 687.616 libssl-1_1-x64.dll
and in OSGeo4W\apps\Python39\DLLs folder there are:
21/10/2021 18:35 3.439.104 libcrypto-1_1.dll 21/10/2021 18:35 687.616 libssl-1_1.dll

Grmpf, tried the patch without success. prgcloud.com
still fails. On a closer look this is (meanwhile?) because its certificate is for www.prgcloud.com
. www.prgcloud.com
and www.python.org
work fine.
import ssl import socket import urllib.request for i in ['prgcloud.com', 'www.prgcloud.com', 'www.python.org']: try: socketHandler = socket.socket(socket.AF_INET, socket.SOCK_STREAM) socketWrapped = ssl.create_default_context().wrap_socket(socketHandler, server_hostname=i) socketWrapped.connect((i, 443)) print(f"ssl {i}: OK") except Exception as e: print(f"ssl {i}: FAIL {e}") try: response = urllib.request.urlopen(f'https://{i}/') html = response.read() print(f"urllib {i}: OK") except Exception as e: print(f"urllib {i}: FAIL {e}")
results in:

Guess the fix for #696 cured this too.

qgis*.vars
doesn't include SSL_CERT_FILE
, hence it's not included in the .env
and in turn not set, when you start the .exe
directly (eg. by using the shortcut). In the shell and QGIS from qgis*.bat
it should work.
