REST API post request being blocked

Hi all,

I have a mobile application that sends a post request and receives a json file. It was working amazingly in http but, after I enabled the https (ssl) with origin certificate, the return are blocked from some messages and I receive an 404 page instead. I checked that replies with around 42kB pass normal but others with around 78kB are blocked. This is my first time using the forum so I don’t have a clear idea of which log files I should include here. Can someone please help me? I was reading something about DDOS protection, would it be the reason of my problems?

Thank you

Additional information: I checked that the server is correctly sending the json in the body of the response.

this is the reply I get when the json file is large:

That is not a block, that indicates that the origin did not have anything to return. The error message you copied is also not a Cloudflare error page, it came from your Origin.

I would start by searching the log files on your origin for the failed requests, and seeing why they returned 404. My guess is there is little in the change in your SSL configuration that would result in occasional 404s, so I doubt the issue is with the SSL config.

Hi Michael,

Thank you very much for your response.I am trying to figure out your information. can you help me further? I am sending the parts from the client and the server.


The client sends an image that is saved in the server side (WORKING). It then wait for the response.


The server receives the image and save it. Then it send to a internal docker for processing. When it receives, I take the json and print it for confirmation. I return the json back to the client and receive the 200 status_code.

I was wondering about the ssl because it was working for more than one moth this way and now, maybe coincidentally when I changed from http to https, it stoped working on larger jsons.

Thank you in advance!

404 is a not found error and the return being blocked both seem like issue from your origin server. You may want to check your server logs at the hosting provider to see if they show the error.


Don’t include any at the moment and if you do, please remove any data you don’t want shared.


I am leaning more towards origin based on what I see in your logs. For anyone downtheline, these links will work on your dash as well; if you go here, https://dash.cloudflare.com/?to=/:account/:zone/security/events and turn the >, you’ll see a block done by browser integrity check (BIC). That’s the only block I noticed and I don’t think that’s the issue you’re having.

You could test to see if BIC is the issue, you can go here https://dash.cloudflare.com/?to=/:account/:zone/security/settings and disable BIC.

If it turns out BIC is the issue, follow the prompt on the dash to create a configuration rule, https://dash.cloudflare.com/?to=/:account/:zone/rules/configuration-rules.

yeeeeeeeeee.

Cloonan, Michael, thank you!!! found out the problem.

I am using portzilla for reverse proxy. THERE IS A TIMEOUT THERE that return 404 when triggered. Just increase the time there and now it works !!!

Thank you!
