I want to connect to my portal in ArcGIS Pro within a Jupyter Notebook using command arcgis.gis.GIS('pro') . This works fine in ArcGIS Pro 2.9 (screenshot 1 below). If I try the same thing in ArcGIS Pro 3.0, an error message appears (screenshot 2 below).
ConnectionError: A connection error has occurred: (Caused by ProxyError('Your proxy appears to only use HTTP and not HTTPS, try changing your proxy URL to be HTTP. See: https://urllib3.readthedocs.io/en/1.26. x/advanced-usage.html#https-proxy-error-http-proxy', SSLError(SSLError(1, '[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1129)'))))
Does anyone know anything here
Best regards
Armin

Solved! Go to Solution.
Could you confirm what version of Server is running the portal? My guess is this is some mismatch between client and portal environment that likely is a bug. ArcGIS Pro 3.0 includes OpenSSL 3, and it has some higher security requirements when authenticating clients.
I haven't heard other reports of this, but it sounds like a technical issue that should be looked at, and may be related to proxy configuration or other settings on top of the version difference. Are you able to log a bug for this issue?
Michael,
I'm running into a similar problem after upgrading ArcPro. How did you resolve it? Thank you!

I have open a Support case to log a bug.
In the meentime i have tested to connect to a Portal for ArcGIS 11 installation (with a self signed certificat). It works with ArcGIS Pro 2.9 but fails with ArcGIS Pro 3.0.1

I found that adding the below parameter to the arcgis.gis.GIS call resolves/suppresses the issue for me.
use_gen_token=True
