Can't connect to Jetpack and XML-RPC is not responding correctly ( 520 )

my website health check shows ‘‘Jetpack is not connected.: 200’’, but I can see Jetpack dashboard and statistical data is working.

so I spent a lot of time trying to find the answer, the following are what I did:

  1. Jetpack debug: XML-RPC is not responding correctly ( 520 )

  2. search ‘’’', and show “Web server is returning an unknown error Error code 520

  3. so I added Cloudflare page rule:“**” to “Disable Security, Browser Cache TTL: 4 hours, Cache Level: Bypass, Disable Apps, Disable Performance”

  4. and added firewall rule: White list : jetpack IPs.

But it’s still not working…
I don’t know how to do, because I already do everything I can do.
Please help me solve the problem. Thanks a lot.
