Cannot communicate with the back-end API. Make sure your API key is valid.

My team have been using AL Object ID Ninja VS Code extension connected to our own Azure back-end for over a year now, until it stopped working, and we started getting the following error notification:

This error shows up after we create a new .al file and start typing object type and a space - i.e. when the extension is expected to call the API. I am not entirely sure when it stopped working due to summer/vacation period, so I cannot say 100% when exactly this became a problem, e.g. how long after the VS Code extension was updated to the newest version by the team members.

As far as I know there have not been any changes to the deployed Azure functions, and I double checked the security keys. Tested with a newly generated pair of keys, but got the same error. Deployed the newest version from GitHub (downloaded today - commit e6d721f, v2.11.1), same same.

Using AL Object ID Ninja - VS Code extension v2.11.1.

I am not sure whether it is an issue with the product, or with our infrastructure/setup, but I would appreciate any tips on how to fix it.
