Why QUIC.cloud?

LiteSpeed Cache plugin of WordPress is always in sync with the QUIC.cloud network and it knows when to invalidate your cache so that end-users won’t receive outdated data from the edge servers, which makes it the only full-page cache CDN for WordPress with an intelligent purge.

It will make your website faster and more secure and your website will be cached on servers all around the world making its response rate faster to end users around the globe. When a user request data from the website, a response will be given from the user nearest located server rather than your main server which is available only in one location, which basically speeds up your website.

Unable to Fetch Server IP

This topic is optional for those who face this error.

Well, There is a chance some of you may have come across this error (shown in the below screenshot). There is no need to worry about it. When you link your site to QUIC account it fetches your Server IP (through your website URL), where your site is hosted, to enable its CDN services. But,

In some cases your website is under a proxy to hide your actual Server IP from its visitors, so QUIC.cloud can not fetch it correctly and shows you this error.

It has a very simple solution, All you have to do is Paste your Server IP (where your site is actually hosted) into the server IP block you see in the below screenshot and Save it.

It will be fixed, Simple as that!

Enjoy Boosted site by QUIC.cloud!
