What is the issue or error you’re encountering

curl on the raspberry pi cannot reach the Cloudflare worker

What steps have you taken to resolve the issue?

I have tried a fresh install of the raspberry pi OS, I have tried to allow the same pi to collect to different workers - all fail.

What are the steps to reproduce the issue?

I’m sorry my technical knowledge is limited. But i have a rapsberry pi in a remote location that uploads an image using curl to a worker on my domain. This has been working for months but suddenly curl cannot reach the cloudflare worker. I have tried to do a fresh install of raspian but still, curl error 35. I’ve tried --insecure at the time of running curl, still fails. Meanwhile, multiple other pi’s at other locations are successfully uploading images via curl to the same worker. The pi that is failing is online and remotely manageable. My suspicion is that cloudflare is ignoring or blocking requests coming from this particular device. Is that possible? Would appreciate any suggestions to help me troubleshoot. Thank you

Hi @seanocaster,

Have you checked your WAF Events page to check if there are any block events that may match your Raspberry Pi? Security Events · Cloudflare Web Application Firewall (WAF) docs

Thanks for the reply. I looked into it but I could not find any details. I have a free account and it seems like the logs are very basic. Is there a specific page or area I need to be looking in?

At the moment I have done a work around. The pi that cannot reach Cloudflare has a script running every 5min to take the photo and then push it to another pi which then uploads it to Cloudflare on its behalf. It is working.

I would love to know what the one pi is just unable to upload to cloudflare.
