Ifly 737 max MSFS I can't use the flight charts on the tablet

Good morning,
I purchased the 737ifly for msfs which has the integration of the navigraph charts on its tablet (I have the navigraph subscription complete with charts), but unfortunately, when I go to click on the part that should open the popup where I can authorize this tablet to use the navigraph charts, it gives me this error that you see and there is no way to use the charts on this tablet. I’ve already written on their official discord but so far I haven’t had any valid answers, I know it’s probably a problem with the plugin that manages the plane, but, in your opinion, what could this problem depend on? I did several tests, reinstalled the plane several times, started the plugin as administrator, but nothing. I would like to point out that with all the other addons the Navigraph authorization has always occurred without problems. Thank you for your possible attention. I remain available for any tests. So it makes sense, the file that appears to handle authorization is navigraphOIDC.dll, which is contained in the ifly plugin folder.

Hi,
We have nothing to do with this and don´t know what the cause of this error could be. Therefore, please contact iFly for deeper information on what this error means. We offer “only” the APIs/Interfaces—the add-on developer implements these APIs, and that is all we have in our hands: the working API but not the logic behind how the third-party add-on uses this API.

The API itself is up and running because we use it on our own, too.

Thank you very much, and I am sorry we are not very helpful in this case.

Cheers,
Richard

PROBLEM SOLVED!

Investigating further I noticed that in my system it was not possible to access 127.0.0.1. Leaving aside technical details, for those who have the same problem as me, here is the solution.

Open Command Prompt as administrator and run the following command: netsh http add iplisten 127.0.0.1
Then start the SIM, load the 737ifly and go to the terminal charts and, as if by magic, the browser for Navigraph authorization will open.
