We recently upgraded to ArcGIS Pro 2.8 and our notebooks that connect to ArcGIS Online have stopped being able to access our proxy host. We've tested in same environment with older install of Pro (2.7) and it works.
We've got a support call in, but it's not getting very far, how would I find out whether there were changes to the proxy host section of the GIS function?
gis = GIS("https://[org].maps.arcgis.com", "[username]", "[password]",proxy_host="dcsproxy.desqld.internal", proxy_port=8080)
ConnectionError: A connection error has occurred: HTTPSConnectionPool(host='[org].maps.arcgis.com', port=443): Max retries exceeded with url: /sharing/rest/generateToken (Caused by ProxyError('Cannot connect to proxy.', OSError(0, 'Error')))
We're experiencing the same issues with both Azure enterprise portals and ArcOnline via the proxy.
It also now errors on our internal enterprise if I try and use the proxy (which used to work, even though it doesn't need the proxy for internal)
Does anyone have a fix?
Saw your post. Can confirm we received an email from ESRI back in June stating it was a bug - BUG-000140337. We're still sitting on 2.7 till it's fixed.
