I am struggling to get the AAO WebAPI to work and am unsure what information you might need to help me figure out what I'm doing wrong. I will try to include as many details as possible.

**My details:**
- Windows 11
- AAO 4.51 b09
- MSFS 2024 (purchased from the Microsoft Store, not Steam)
- Default installation location
- I’ve created inbound and outbound rules for AAO and for ports 43380 and 43381
- I’ve completely disabled the Windows firewall
- The AAO LEDs in the bottom-right corner indicate that the WebAPI is listening
- MSFS 2024 is open (not in a menu) and sitting on the runway with a flight plan loaded
- I’ve memorized the troubleshooting guide from [this link](https://www.axisandohs.com/uploads/6/0/8/2/60827113/axisandohs_webapi_troubleshooting.pdf)
- When I try to visit the URL listed in the “Change WebAPI Address” dialog box (http://192.168.4.76:43380), I get this error:

  **This site can’t be reached**
  192.168.4.76 refused to connect.
  Try:
  - Checking the connection
  - Checking the proxy and firewall
  - ERR_CONNECTION_REFUSED

- WebFPI seems to work fine and will display preconfigured gauges without any issues or errors
- I’ve tried both localhost and the local IP address with the same results

I’ve tried searching YouTube and even consulted several AI platforms for insights, but no success so far. I would really appreciate any help.

I’ve restarted and rebooted, but the issue persists.

I have attached some screenshots.  Thank you in advance!

That is as expected, this is just a web service. Unless you send proper request parameters, the API doesn't know what to respond - so it won't repsond at all. Normally I would expect "404 Not found", but who knows.

You still haven't explained what you are planning to do with the WebAPI, what do you need it for? Why are you doing this, what do you expect to happen? What is the actual problem that makes you want to tinker with the WebAPI?

This is incorrect. You have to create rules for the TCP ports themselves, not for the application. Port rules are independent from the AAO application.

Btw. about 1.-> These checkboxes have no meaning, none at all. They do not indicate that something has been turned on or off. Their one and only purpose is to select datasets in the list that you want to change with the buttons below.
(the checkbox you are pointing at is a simple "check all - uncheck all" it too has no bearing whatsoever on the WebAPI)
