Causes

  • There are too many requests queued on Cloudflare’s edge that are awaiting process by your origin web server. This limit protects Cloudflare’s systems.

Fixes

Step 1: Accept Incoming Connections

Tune your origin web server to accept incoming connections faster.

Step 2: Adjust Caching Settings

Adjust your caching settings to improve cache-hit rates so that fewer requests reach your origin web server.

Step 3: Contact NET Support

Reach out to NET support or web administrator for assistance.
