Failing to Call Server with HTTPS

Hello, I'm trying to create a application that calls a server that is mine. I have a domain with a valid certificate (not self signed). 


When I test the connection in the app creation screen on https://developer.lametric.com I get a error that I can't connect to the server... If I use http the connection is made. Please note that I have tested the https connection in the browser and in other apps and it works.


Is this possible? Can any one help me? The server that is receiving the request is a NodeRed instance (should be irrelevant) and the income is handled by a reverse proxy that ensures that the connection is in https and passes it to the server. This processes is working in the browser, but failing in the developer.lametric url validation.


Thank You


Here are a few suggestions to help troubleshoot and potentially resolve the issue:

Check CORS Settings: Ensure that your server's Cross-Origin Resource Sharing (CORS) settings allow requests from the LaMetric domain. This might be preventing the connection from being established.

Verify SSL Certificate: Even though your certificate is valid, double-check that it is properly configured for your domain and not missing any intermediate certificates. Tools like SSL Labs can help diagnose certificate issues.

Firewall/Network Configuration: Ensure that there are no firewall rules or network configurations blocking requests from LaMetric's servers to your domain.

Log Requests: Set up logging on your reverse proxy and NodeRed instance to capture any incoming requests and errors. This can provide insight into what might be failing during the connection attempt.

Test with CURL or Postman: Use tools like CURL or Postman to manually test the HTTPS connection and see if you receive any error messages that might help identify the issue.

Contact LaMetric Support: If the issue persists, consider reaching out to LaMetric’s support team for assistance. They may have specific insights or requirements for their developer platform.

Hopefully, one of these suggestions helps you pinpoint the issue!
