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?

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.

Hi, thank you for the answer
For me it will not fix the problem. I will now get a response:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>301 Moved Permanently</title> </head><body>
But as this is not really Thingspeak issue, then I will figure out something else. Parsing the page directly for example.

@Egert V: You could use a MATLAB Analysis app on ThingSpeak with the WEBREAD and URLFILTER functions to parse the data. Give it a shot!
