Hello team,
i am performing Duo integration with RA VPN using MFA, however it is failing on last step to make it working. Connection towards Duo Cloud from Active directory Windows 2012 R2 that runs Duo Authentication proxy is failing. Note that AD does not have an direct connectivity and needs proxy connectivity. Proxy settings has been configured in [main] configuration section.

==============================================================================
If i do not define proxy settings in [main] section than the connectivity to Duo Cloud will provide failure on TCP timeout. So it’s seems that proxy settings are right now enforced, however not sure why the RestAPI query is still failing.
I have went through following connectivity checks:
https://help.duo.com/s/article/1336?language=en_US
So question is, what connectivity tool checks are being executed since when i access Duo Rest API call manually over browser, all seems to go fine via proxy as i am getting valid certificate issued by Duo.
Additionally, how can I interpret following message:
" The connectivity tool unfortunately doesn’t use the proxy parameters in the [main] section to then test the rest of the sections present in authproxy.cfg
, giving a potentially misleading result from that tool. We definitely have plans to fix this."

May thanks for any hints.
