I'm stuck, help needed

The HTTPSRequest example works perfectly without any modifications.
Then I modified it to load some stuff from my webserver.
Loading a .json file works as expected
Then I try to load a php file that outputs the same simple json, and this keeps failing. This .php is just echoing exactly the same json as the .json file, no errors, but can't figure out the difference.

https://moveadot.nl/test/json.json

Thanks in advance

When adding


it outputs,

HTTP/1.1 200 OK
Date: Wed, 24 Apr 2019 07:50:59 GMT
Server: Apache
Connection: close
Transfer-Encoding: chunked
Content-Type: application/json
X-TransIP-Backend: web758
X-TransIP-Balancer: lb0

42
{"state":"success","ip_local":"192.168.0.25","post_id":1234456789}
0

So I'm wondering, what are the 42 and 0, and how to extract just the json data.
Any insight would be appreciated

Hello,
I am trying te extract data from my weather station that posts to WunderGround. I have searched www for code and this is the best so far however I cannot get it to load the data from the API.
Connection to my wifi is successful however however it returns the following text:

22:05:03.487 -> WiFi connected
22:05:03.487 -> IP address:
22:05:03.487 -> 192.168.20.243
22:05:03.487 -> connecting to https://api.weather.com/v2/pws/observat ... on=decimal
22:05:03.536 -> Using fingerprint 'D4 81 63 98 5D 9E 06 06 85 C8 FE 8F 10 E8 FF DB B5 91 94 E0'
22:05:03.536 -> connection failed

I am really stuck. I have searched www for answers and this code is the best so far. Can someone please help me with what I am doing incorrectly? My code is below:

Thanks for any pointers in advance
