Problem with XDS Server Connection when changing Port (student project)

Hi,

I'm a student trying to build the "Hello World" application (https://docs.automotivelinux.org/docs/en/master/devguides/reference/xds/part-1/create-app-get-source-files.html) for the Renesas H3 Starter Kit (h3ulcb) using AGL XDS.

Therefore, I try to follow the steps on https://docs.automotivelinux.org/docs/en/master/getting_started/#developing-an-application but I am stuck on the step where the SDK is installed which is step 3 of "Get Ready to Create Your Application" (https://docs.automotivelinux.org/docs/en/master/getting_started/reference/getting-started/app-workflow-prep-app.html#using-xds).

Following the instructions at https://docs.automotivelinux.org/docs/en/master/devguides/reference/xds/part-1/install-sdk.html,  I put my self-built SDK installer into the $HOME/xds-workspace/sdks directory. But using the XDS to install the SDKs does not work.

XDS Dashboard:

When I start the XDS Dashboard and go to "SDKs" > "SDKS MANAGEMENT" it says "No data found" and I cannot choose any SDK for installation.

Command Line:

The command: 'xds-cli sdks ls -a -l' returns "No XDS Server connected"

The command: 'xds-cli sdks install --file $HOME/xds-workspace/agl/sdks/poky-agl-glibc-x86_64-agl-demo-platform-crosssdk-aarch64-toolchain-6.0.4.sh -l' returns "No XDS Server Connected" as well.

For the XDS Server I used the Docker container solution (https://docs.automotivelinux.org/docs/en/master/devguides/reference/xds/part-1/server-part.html#docker-container ). I had to change the port to 8001 because 8000 did not work:

bash ./xds-docker-create-container.sh -id 1

I also changed "8000" to "8001" in the config files: /etc/xds/agent/agent-config.json and /etc/xds/server/server-config.json.

Is there anything wrong with the XDS Server or Client maybe?
