Hi, @jokuja. Our support team can troubleshoot Netlify specific issues but we are not able to troubleshoot your NGINX reverse proxy.
Someone else may be able to answer you questions here but our support team has a specific scope of support.
Now, I can troubleshoot specific HTTP requests made to our service because that is Netlify specific. I can tell you what the requests look like from our side and this might help you to find the root cause.
If you have the x-nf-request-id response header for the HTTP response or responses that our CDN returns, then I can find the HTTP request we received for it.
There more information about this header here:
If that header isn’t available for any reason, please send the information it replaces (or as many of these details as possible). Those details are:
- the complete URL requested
- the IP address for the system making the request
- the IP address for the CDN node that responded
- the day of the request
- the time of the request
- the timezone the time is in
If there are questions about any of this, please let us know.
