/var/lib/jenkins/workspace/brave-browser-build-linux/src/brave/vendor/requests/requests/packages/urllib3/util/ssl_.py:90: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail.

  InsecurePlatformWarning

Description from https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning:

InsecurePlatformWarning
This happens on Python 2 platforms that have an outdated ssl module. These older ssl modules can cause some insecure requests to succeed where they should fail and secure requests to fail where they should succeed. Follow the pyOpenSSL guide to resolve this warning.

Really shouldn't be ignoring these, can we change the ticket to resolving the ssl issue? (apologies if that's what you meant)

[RyanJarv]

There's a ticket to switch to python3 I believe, maybe makes sense to combine it with that?

[mbacchi]

Oh, ya I meant 'fix the problem with ssl that is causing these warnings', sorry if I wasn't clear about that. I'll change the title.

On Mac, this exhibits a slightly different InsecureRequestWarning:
