[mlbrack]

One day, Cloud Plugin worked, next day it didn't.

Returning python error on attempted logon.

Uninstalled all QGIS and python. Reinstalled. Plugin still failing.

Hello @mlbrack - does the problem still occur? If yes, then could you please take this to QGIS Cloud Support?

[mlbrack]

Yes, still fails. Thanks. Just started a ticket.

[HusseinKabbout]

It seems that setting SSL_CERT_FILE environment variable fixes this problem.

This is how I set the SSL_CERT_FILE variable:

1. In QGIS go to Settings/options
2. Then go to the System Tab
3. Unter Environment check the checkbox and add a new entry like the following picture:

The path might be slightly different for you, since you probably installed QGIS somewhere else.

But this workaroudn only works in the upcomming QGIS version 3.22.0.

[mlbrack]

Interesting. So this is a known problem? I have two machines that are identical in OS and QGIS installs. One is failing. One is not. Thanks for the info.

[HusseinKabbout]

Interesting. So this is a known problem?

I just found this workaround today. I don't know if this is a known problem.

I have two machines that are identical in OS and QGIS installs. One is failing. One is not.

Are you sure that the QGIS versions are identical? Can you send a screenshot of both Version dialogs?

[mlbrack]

My QGIS versions aren’t identical anymore from various installs/uninstalls to test. This occurred in 3.16 updated to 3.20 to try to resolve. Updated, uninstalled, reinstalled cloud plugin. In jpgs, the 3.20.3 is the machine that is getting the python error.

[tpo]

Similar past problem on OSX, due to missing cert.pem file in package: #36

[tpo]

@HusseinKabbout suggest, that this might be related to qgis/QGIS#45377 but I think that's a different problem (namely version.qgis.org having a mess with their certificates).

[tpo]

According to @HusseinKabbout this is the problem:

• https://trac.osgeo.org/osgeo4w/ticket/696
• jef-n/OSGeo4W@041537b

[tpo]

@mlbrack could you please test if the new development build https://qgis.org/downloads/QGIS-OSGeo4W-3.22.0-1.msi fixes your problem?

[HusseinKabbout]

I have tested both QGIS 3.16.12 and QGIS 3.22.0 and they are working now for me. @mlbrack can you confirm this and close this issue?

[mlbrack]

I have uninstalled all and reinstalled 3.22.0
Uninstalled and reinstalled qgis cloud plugin.
Ran using default and ran using manually configured SSL_CERT_FILE.
Used standalone installer and OSGEO4W installer.

All returns the same set of errors.
