What is the issue you’re encountering
Cloudflare is blocking traffic.
What steps have you taken to resolve the issue?
Unfortunately, the previous ticket on this was resolved (?) and closed before the investigation was complete.
The IP address and ray ID data was provided to FR24 and they saw no evidence that the traffic was getting through. All indications are Cloudflare is blocking the traffic. This could possibly be because Cloudflare has changed to a 384 bit ECC which is not supported on my side.
Here is the debug information from my IoT. I’ve been told this indicates SSL decryption is successful, but it appears to be not so.

Was the site working with SSL prior to adding it to Cloudflare?
Yes
What is the current SSL/TLS setting?
Full (strict)
What are the steps to reproduce the issue?
Not sure what the question above means.
The previous solution (?) stated FR24 needed to search the logs using the ray IDs to find out why the traffic was blocked. FR24 found no evidence of any traffic.
