Hi there,
I have to mention, that a POST with Tasker allready worked for me on my old Android.
(Even used the new “HTTP Request” not “HTTP POST”)
Now I have entered everything the same on the new Phone and I get TimeoutException.
Inside API-Security I have enabled “implicit userroles” (default)
…and even “basic auth” for testing (but did not help)
Test with another REST App on the “critical” phone works. Same as Postman on the Laptop. (Both without any API Token 
Here are my Details that are 99% identic on both phones. (accept the key)
-------------------Tasker--------------------
Method: POST
URL: http://192.168.1.11:8080/rest/items/presence
Headers: Accept:application/json Content-Type:text/plain
QueryParameters: access_token=oh.androidTasker.98rkdre67****************
Body: OFF
Timeout: 30sec
Trust Any certificate: true
Structure Output (JSON, etc) : true
Continue Tasker if fails: true
What might be wrong?
