ArcGIS Notebook error gis = GIS("home")

[Oiligriv]

Hello Community
I'm experiencing an anomaly on ArcGIS Notebook Server 11.1.
when I run the first notebook with just the command gis = GIS("home") I get the following error

---------------------------------------------------------------------------

Notebook Server is installed on Ubuntu 22.04
and the docker is the CE version

• SSL certificates have been installed
• the PrivatePortalURL has been enhanced
• The hosts files are compiled correctly
• the init_param.sh file has been compiled with Proxy info
• the /etc/enviroment file is compiled with the proxy info

with the arcgis user in linux if I execute a CURL -K of the private portal url everything works correctly

What could it be?

Thank you

I discovered the error.
essentially docker images by default, don't read the server's local Hosts file.

How do you think I can edit the hosts file for Esri's docker images?

Thank you

[ChristopherPawlyszyn]

You should be able to use the dockerExtraHosts system property configured via Notebook Server Admin, check out the API documentation here.

[StefanUseldinger]

I don't understand the documentation to its full extent. Which hosts have to be added to the dockerExtraHosts? The Portal, a DNS,...?

I had a similar error on ArcGIS Notebook Server 11.1, but with another error code.

ConnectionError: A connection error has occurred: HTTPSConnectionPool(host='pvm-portal.esri-cis.com', port=7443): Max retries exceeded with url: /arcgis/sharing/rest/portals/self (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x000001F9A9F49970>: Failed to establish a new connection: [Errno 11001] getaddrinfo failed'))

Adding the ArcGIS Portal host to the dockerExtraHosts variable does not solve the problem - the error remains. Please - what could be wrong? @ChristopherPawlyszyn

dockerExtraHosts variable doesn't work for me. Registering internal ip of portal in our dns solved the problem. ArcGIS Notebook Server with Windows containers can't work with ip's listed in hosts file on the host.
