AI Python SDK inside a docker container doesn't send about applicationinsights-python

[FunksMaName]

The Python SDK is now on version 0.11.7, 6 whole months in and it's still the same old story with this bug when running on "windowsservercore:ltsc2016" docker images, as usual, well played Microsoft.

@reyang can you take a look? If you plan to re-use this channel in OC - you will likely hit this issue

Thanks @SergeyKanzhelev. I don't plan to re-use the channel.

The bug is occurring here due to SSL certificate exception:
https://github.com/Microsoft/ApplicationInsights-Python/blob/0e8342023f79e422cb718ade544bc34af9baf6d3/applicationinsights/channel/SenderBase.py#L136
<urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:852)>

This is a known issue with Python in Windows Docker container:
https://bugs.python.org/issue36137

The prescribed temporary workaround which worked for me was the following:
certutil -generateSSTFromWU roots.sst && certutil -addstore -f root roots.sst && del roots.sst

Hi @reyang, I'm running into the same issue on Docker; tc.flush() hangs on forever.

Is there any solution for this? The request never seems to time out.

When I force exit the program, I get the following output:
