Dear community,

I am currently working on integrating weather forecast data from open-meteo.com API using the LHTTP_Get function block. I have downloaded the root certificate from the open-meteo.com website and successfully imported and installed it into theTrusted Certificates and Root Certification Authorities in TIA Portal.

However, I am encountering issues when attempting the HTTPS GET request. I've attached a screenshot showing how I'm calling the LHTTP_Get function block, including all parameters and the return code.

If anyone has experience with similar implementations or has encountered this issue before, I would greatly appreciate your suggestions or troubleshooting tips.

Thank you in advance for your support!

P.S. You can find the following screenshots in the pdf in the attachment.

Dear Towome,

Thank you for your prompt response.

I followed your instructions, but unfortunately, I'm still encountering an error—this time it's 16#80E1.
I've attached screenshots of my current settings for your reference. Could you please take a look and let me know if you spot any mistakes?

Looking forward to your guidance.
