Hi
Website where I was getting information with ThingHTTP now returns -1 when not using any parse string. Is thingspeak now blocked by the webpage? How can I get it working again?

I would inspect the source at the target website. That is the most likely cause. Can you share the ThingHTTP content?

Method: GET
Content-Type: application/json
HTTP Version: 1.1

It appears that the certificate chain of the website may have an expired or invalid certificate or it is not from a recognized certification authority. You will have to change the request from HTTPS to HTTP so the certificate is not verified by the ThingSpeak servers. Change URL in ThingHTTP from https://<YOURSITE> to http://<YOURSITE>. For more details, see here: https://www.securityweek.com/expired-lets-encrypt-root-certificate-causes-problems-many-companies
NOTE: Using HTTP instead of HTTPS is strongly not-recommended. Ideally the maintainer of the website in question is able to update their site certificate chain.
