Problems caused by bintray sunset

[R-n-R]

Executing the first example command produces an error:

boost/1.74.0: Not found in local cache, looking in remotes...
boost/1.74.0: Trying with 'conan-center'...
ERROR: HTTPSConnectionPool(host='conan.bintray.com', port=443): Max retries exceeded with url: /v1/ping (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed:

1. Make sure the remote is reachable or,
2. Disable it by using conan remote disable,
Then try again.

It's probably caused by this: https://blog.conan.io/2021/03/31/Bintray-sunset-timeline.html Interestingly these warnings are older than the talk from which I'm playing with these and on the video we can see that boost was downloaded without problems. https://youtu.be/fu-ayefRqWM?t=1411

And unfortunately following this: https://docs.conan.io/en/latest/uploading_packages/remotes.html

One gets:

boost/1.74.0: Trying with 'conancenter'...
ERROR: HTTPSConnectionPool(host='center.conan.io', port=443): Max retries exceeded with url: /v1/ping (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:1076)')))

1. Make sure the remote is reachable or,
2. Disable it by using conan remote disable,
Then try again.

The windows example works without problems btw and starts of with the proper remote and that remote is accessible without problems too.
