Wordpress LScache Plugin: QUIC.cloud CDN Error 520 and 524
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi, This is exaqctly the same error that I was getting earlier. It probably has been a year since it last happened. Here is the link to the thread: https://wordpress.org/support/topic/quic-cloud-cdn-error-520-and-524/ Basically, I keep getting error 520 when trying to access any page on three of my websites hosted on a Litespeed server. The error page shows this message: The QUIC.cloud server AS-IN-BOM-297 was not able to connect to the sites origin server. you can get it in toolbox -> report , click send to LiteSpeed I cant provide a report number because I cant log into the Admin area of my website. What should I do? Thanks. Hi, you can go to QC dashboard -> CDN -> bypass CDN , this will disable CDN and allow you to access wp-admin 520 error usually happens because CDN nodes failed to connect your origin server , a typical reason is firewall please make sure you have whitelist QC IPs in your firewalls https://quic.cloud/ips Best regards,
