Custom GPT: "message": "The requested action requires approval

Before I go in: Yes, I know there are some of those things discussed in 2023, 2024 AND, I’ve researched ALL of them already.

Problem: Debug Info of Custom GPT shows that the function call needs approval

Does anyone else now encounter all of a sudden something similar?
Your custom gpt tries to call a function and suddenly you get this:

Done Manual Tests

When trying from my server (no matter if locally or online)

I get this for example:

{"message":"Memory server is operational.","status":"success"}

No errors. Works fine. Each time. No matter how fast and how many times I am calling it. Flawless

BUT, if my custom server tries it:

[debug] Calling HTTP endpoint
{
  "domain": "<static (fix) ngrok domain I am using online>",
  "method": "get",
  "path": "/memory/test",
  "operation": "testMemoryServer",
  "operation_hash": "bbadee4157726684fd554633169eeee86c91b139",
  "is_consequential": false,
  "params": {}
}
[debug] Response received
{
  "function_name": "testMemoryServer",
  "domain": "<static (fix) ngrok domain I am using online>",
  ***"message": "The requested action requires approval",***
  "action_id": "g-3a2a4cb2b6c1aec159f48ade0e16cb2fbe5a0299"
}

WHY does it need APPROVAL all of a sudden when it always worked before?
Anyone else facing the same?

The code didn’t even change since the end of last year for this.
Even in early January this year I used it for the last time. It worked.

Constellation

The server was running on my local computer.
The tunnel was created by ngrok command like this:

.\ngrok.exe http 5000 --domain <samedomain as above>

The token

ngrok config add-authtoken <authtoken>

is also still valid and has been set.

Those are the results from manually testing. Locally AND, preferrably, online.

Anyone got any clue or a similar or the same problem? Still wasn’t able to solve it, yet.
