Hello there,
I’ve been getting 504 errors using the moralis JSONRPC on mainnet.
After I had a helpful chat with Kresimir, we both realized that I am bellow the rate limit threshold. He reported that my application was doing:
- last 5minutes: 195
- last hour: 1,758
- last 24hours: 101,798
- Last week: 779,325
And the Free rate limit supported is 3,600 req/min
I suspect I am being throttled by cloudflare when picking out the error bellow:
<h2 class=\"text-3xl leading-tight font-normal mb-4 text-black-dark antialiased\" data-translate=\"what_happened\">
What happened?

Using the same JSONRPC endpoints on my local dev, I was not able to reproduce. However I am consistently getting the errors on each heartbeat (request) my production app performs which is set to every minute. I am hosting on heroku, if that’s a clue.
Find bellow the full error, let me know if there is anything else you will need from me, apologies for the error being unformatted, I got it from heroku logs:
