 * Hello
 * I’m using the plugin on a non LSWS.
 * Is there a log file for requests made by the CDN to my server ?
 * My hosting provider is asking for a log to help me fix the 520 Error.

 * 520 error usually indicates the CDN server failed to contact to origin server
 * please ask your provider to check any incoming requests featured with header `
   CDN-Loop: QUIC.cloud;EU-ES-MAD-32` that last part is the incoming node
 * or `x-qc-country`
 * they can also filter by IPs [https://quic.cloud/ips](https://quic.cloud/ips)
 * usually we would suggest our IPs to be whitelisted by the firewall or similar
   to avoid issue.
