Error publishing to connect server, too many redirects

[pelacables]

Hi all,

I'm facing an issue while trying to publish a python app from jupyterhub to a connect server hosted in the same network.
We have a company proxy configured as environment variable:

NO_PROXY=localhost,*.company_domaincom,10.,10.*,172.20.,172.20.*,0,1,2,3,4,5,6,7,8,9
HTTPS_PROXY=http://proxy:80
no_proxy=localhost,*.company_domaincom,10.,10.*,172.20.,172.20.*,0,1,2,3,4,5,6,7,8,9
https_proxy=http://proxy:80

and when trying to publish it says:

If I unset the proxy, it works.
Seems like it does not honorate the NO_PROXY env variable?

Thank you for reporting this. rsconnect-jupyter uses rsconnect-python's API layer to access the server. NO_PROXY support was recently added there with this PR so it will be present in the next release.
