Unable to connect to portal from ArcGIS Pro after Windows hardening

shamnasPC — Mon, 05 Dec 2022 06:37:16 GMT

Hi,

I am unable to access Portal (10.9.1) from ArcGIS pro 3.0.2 after Windows hardening. When I try to connect, I get the following message: Unable to add portal. Please make sure that the specified portal is up, running and the portal url is correct. However Portal is accessible from browser.

Any ideas what might be causing the issue?

Thank you,

Shamnas

@shamnasPC ArcGIS Pro is self-certified and compliant with Windows Hardening.

https://trust.arcgis.com/en/security/arcgis-desktop-best-practices.htm

Check the obvious like URL and credentials. Since, Portal is accessible from browser - site is allowed/white listed.

Use a tool like fiddler to track web traffic, identify blockage and allow for the portal connection (log Esri Support ticket if needed). Contact your IT Security admin as there are granular configuration settings/Group Policy settings for Windows hardening that may need to be tweaked.

Thanks @AyanPalit

Yes, I have tried with Fiddler , and getting below error on the request

request: /gisportal/sharing/rest/portals/self?f=json HTTP/1.1

Response: HTTP/1.1 301 Moved Permanently

So I tried to enable HTTPS only and remove http from IIS, started getting 502 response now, also identified that Pro is always using http to request /gisportal/sharing/rest/portals/self?f=json. Please note, hostname is added to in the host entry to be able to access to portal from the server.

The Portal connection string in ArcGIS Pro should use https. Other capabilities like sharing inherit the appropriate URL's.

Hi @AyanPalit

Yes I am using https, The error in fiddler looks like this

"After the client received notice of the established CONNECT, it failed to send any data"

This is happening only when I connect with Pro, But through browser all good

I have the same problem with adding the ArcGIS Portal 11.1 to the ArcGIS Pro 3.1.2 when both are installed on the same Windows Server 2022 Datacenter. I could add this AGE portal from P{ro that is installed on an external to AGE machine. I use https:\\ . Are there any suggestions to try?
