Description

I want to trigger a GitHub actions dispatch workflow from my esp32 using HTTPClient.

It's working perfectly using curl with :

curl -L -X POST https://api.github.com/repos/mickahell/robots-data/dispatches \
    -H "Accept: application/vnd.github+json" -H "Authorization: token ${TOKEN}" \
    -d '{
        "event_type": "watchy-data",
        "client_payload":
        {
            "data-name":"steps", "date":"01-01-1970", "hour":"00", "data":"7000"
        }
    }'

But I'm always getting an error -1 connection refused from the esp32.

Github does redirections. Don't know if this needs explicit allowed in code?

The problem was from my way to check if the network is on.
The code in the issue works fine
