Issue Report: GitHub Action fails to run Power Platform Solution Checker (Advisor endpoint unreachable: microsoft/powerplatform-actions/check-solution@v1)

[mtrqq8h2h5-hue]

Hi Team.,

**Issue Summary: **
We have followed the steps and configured the powerplatform-actions for check-solution.
The GitHub Action Power Platform Solution Checker (microsoft/powerplatform-actions/check-solution@v1) fails with a non-recoverable error when attempting to contact the Power Apps Checker (Advisor) API. The error occurs consistently across all tested geographies (Australia / United States / Europe / Asia).

**Repository & Workflow: **
Microsoft Repository: https://github.com/microsoft/powerplatform-actions/tree/main/check-solution
Workflow: GitHub Actions – Solution Checker
Action: microsoft/powerplatform-actions/check-solution@v1

**Workflow Step: **

• name: Run Power Platform Solution Checker
  uses: microsoft/powerplatform-actions/check-solution@v1
  with:
  environment-url: ${{ vars.PP_DEV_ENV_URL }}
  user-name: ${{ secrets.PP_DEV_USR }}
  password-secret: ${{ secrets.PP_DEV_PWD }}
  path: ${{ inputs.solution_unique_name }}.zip
  geo: ${{ inputs.geo }} # tried Australia / United States / Europe / Asia

**Observed Behaviour: **
The action authenticates successfully.
When invoking Solution Checker, it attempts to reach the Advisor API endpoint, which is failing.

**What We Tried: **
Changed geo parameter to multiple values (Australia, United States, Europe, Asia) — same failure.

Example: https://australia.api.advisor.powerapps.com/
We have also tried by changing the different geo locations: ({geo}.api.advisor.powerapps.com).
https://unitedstates.api.advisor.powerapps.com/,
https://europe.api.advisor.powerapps.com/,
https://asia.api.advisor.powerapps.com/

Tested from:

GitHub-hosted runners (public internet)
Corporate network (local tests)

Authentication to environment succeeds.
In both cases, {geo}.api.advisor.powerapps.com appears unreachable.

Expected: Solution Checker analyses the solution and produces a report.
Actual: The job ends during the Advisor call, and no results are produced.
