Resolving "Unable to Connect to the Remote Server" in PowerShell with Docker

Recently, I encountered an issue while working on a project that involved PowerShell and Docker. The error message was:

Waiting for CM to become available...

Invoke-RestMethod : Unable to connect to the remote server

At C:\Projects\Project.Web\up.ps1:121 char:19

+ ...   $status = Invoke-RestMethod "http://localhost:8079/api/http/routers ...

+                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    + CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebException

    + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand

Fix - Issue got fix with below steps

This error indicated that my PowerShell script could not connect to the server at http://localhost:8079/api/http/routers, which was crucial for the project's functionality. After some investigation, I discovered that the problem was related to the Docker network configuration.

Here is how I resolved the issue:

Step-by-Step Solution

List Docker Networks:

First, I needed to identify the existing Docker networks. This can be done using the following command:

docker network ls

This command lists all the networks created by Docker. The output should look something like this:

NETWORK ID          NAME                DRIVER              SCOPE

9b73baa9dff4        bridge              bridge              local

2c2b1a85c1a2        host                host                local

3e8e8a1c32b4        none                null                local

7e8f1b1d3f44        my_project_network  bridge              local

Remove the Project Network:

After identifying the network associated with my project, I removed it using the following command:

docker network rm <name_of_network>

For example, if the network name was my_project_network, the command would be:

docker network rm my_project_network

Run the up.psl script again
