Describe the problem/error/question

I have a workflow to create a report, and after 2 months of it working, I now get an error when running a second API call with Smartlead. I tried multiple ways of batching and time out but it does not solve the problem.

What is the error message (if any)?

Gateway timed out - perhaps try again later? [item 60]

server.smartlead.ai | 504: Gateway time-out Gateway time-out Error code 504 Visit cloudflare.com for more information. 2025-05-26 10:02:14 UTC You Browser Working Frankfurt Cloudflare Working server.smartlead.ai Host Error What happened?

The web server reported a gateway time-out error.

What can I do?

Please try again in a few minutes.

Cloudflare Ray ID: 945c6f508ee965b0 • Your IP: Click to reveal 20.52.126.13 • Performance & security by Cloudflare

(function(){function d(){var b=a.getElementById(“cf-footer-item-ip”),c=a.getElementById(“cf-footer-ip-reveal”);b&&"classList"in b&&(b.classList.remove(“hidden”),c.addEventListener(“click”,function(){c.classList.add(“hidden”);a.getElementById(“cf-footer-ip”).classList.remove(“hidden”)}))}var a=document;document.addEventListener&&a.addEventListener(“DOMContentLoaded”,d)})();

Please share your workflow

I tried but it tells me I can only share a max of 5 links in the message.

Hello,

Seems like maybe cloudflare is limiting your connections now, my guess it that server.smartlead.ai has changed their firewall rules in cloudflare or somehow ure IP is linked to bad request and could be getting blocked now.

It could also be because it’s a 504, that the actual server is having issues, worth reaching out to smartlead, with the rayid of 945c6f508ee965b0, they can use this to check why it was blocked or not available.

Hope this helps.
