Enabling QUIC.cloud services¶

In order to use QUIC.cloud, you must pair it with WordPress. Here's how to pair LiteSpeed Cache and QUIC.cloud in your WordPress admin.

Enable QUIC.cloud service¶

Log in to the WordPress dashboard for the domain you’d like to use with QUIC.cloud. Navigate to LiteSpeed Cache > General > Online Services, and click the Enable QUIC.cloud services button.

QUIC.cloud will attempt to detect your server type and IP. Wait a few moments for this to complete.

The next step is to create a QUIC.cloud account. However, you only need to do so if you plan to use the CDN. An account is optional, if you only plan to use the QUIC.cloud Online Services for WordPress.

There are benefits to a QUIC.cloud account, including a dashboard where you can:

• See detailed usage, statistics & errors for all services
• Have the ability to increase the quota limits with an account-level credit balance
• Set up & manage all QUIC.cloud CDN options
• Easily open a QUIC.cloud support ticket
• Manage multiple domains in one place

If you wish to use QUIC.cloud anonymously, then you can click the Stay Anonymous button, and your setup is complete. You may begin using Image Optimization, Page Optimization, and other QUIC.cloud non-CDN services immediately.

Otherwise, you can move on to the next step.

Create a QUIC.cloud Account¶

You should still be looking at the Create an account to link WordPress site dialog box from the previous step. This is where you either create a new account, or log in to an existing account.

Set up QUIC.cloud¶

Enter your email address, choose a password, agree to the QUIC.cloud terms and conditions, and click Register. Check your email for a validation message from QUIC.cloud, and confirm your account by clicking the activation link within.

Your QUIC.cloud-WordPress connection is complete!

The next step depends on whether you want to use the CDN or not. If you do not, you can Finish Link Setup. Otherwise, you will Enable the CDN.

Finish Link Setup¶

If you don't intend to use the CDN, you can click the Finish Link Setup button.

You will be returned to the LiteSpeed Cache > General > Online Services page in WordPress, which should now indicate that QUIC.cloud Integration is Enabled.

In the example above, since we clicked Finish Link Setup without enabling the CDN, you will notice that the CDN service is disabled. All of the other optimization services are ready to use.

Your setup is complete. Welcome to QUIC.cloud!

Enable the CDN¶

You should still be looking at the Enable CDN dialog box from the previous step.

Press the Enable CDN and continue with setup button.

It's now time to set up your DNS.

Point your DNS to QUIC.cloud¶

If you plan to use QUIC.cloud CDN, you must point your domain's DNS in our direction. You can either do this by updating CNAME records, or by switching to our own QUIC.cloud DNS service.

For the purposes of this guide we are going to assume you wish to use QUIC.cloud DNS. If this is not the case, please see our DNS documentation for other options.

Select I want to use QUIC.cloud DNS and press Continue.

Import Existing DNS Records to QUIC.cloud¶

QUIC.cloud will attempt to detect your domain's DNS records and import them. Please be patient while it works, and don't close the window during this time.

Once detection is complete, you will be asked to confirm that your DNS information is correct. Accept all of the detected records, or uncheck any that you no longer need, and click the Add DNS Zone button.

Update Your Nameservers¶

Once your DNS records have been imported into QUIC.cloud, you will need to instruct your domain registrar where to find your DNS records.

QUIC.cloud will attempt to verify that your nameservers are correctly set up at your domain registrar.

Your domain registrar is the the provider you purchased your domain name from. Sometimes this is the same as your hosting provider, but that is not always the case. Make sure that you are in the right place before you change anything!

Log in to your domain registrar. Your previous DNS provider's nameservers should still be on file. You'll see them listed under NS1, NS2, and possibly NS3 and NS4 as well.

If your domain is registered with one of these providers, you can click the appropriate link below to follow their instructions for adding custom nameservers:

• Hostinger
• GoDaddy
• Namecheap

If your registrar is not listed above, you'll need to look for the area of their site which allows you to manage Nameservers. It may be called "DNS Zone" or "Manage DNS" or something similar.

Change the NS1 and NS2 records, to match those displayed in the dialog box under Nameservers assigned to your domain. If your domain registrar has additional records (NS3, NS4, etc.) erase those values. You should now only have QUIC.cloud-provided NS records at your domain registrar.

Click the Finish Link Setup and go back to WordPress button.

Verify DNS¶

After the above steps are complete, you can check the status of your domain's DNS with a tool like DNSChecker.org. There are typically delays due to DNS caching, but if your DNS has still not propagated after 24 hours, please open a support ticket and we'll look into it.

Allowlist QUIC.cloud IPs¶

You're almost finished! In order for QUIC.cloud to perform its services, it needs to be able to communicate with your origin server. Some server-level and application-level firewalls may interfere with this communication. If you have one of these firewalls in place, you will need to make sure it is allowing QUIC.cloud IP addresses.

Please see Adding QUIC.cloud IPs to Allowlist to continue.

Verify the CDN is working¶

Here's a simple way to tell if QUIC.cloud CDN is serving your site: Use the LSCache Check tool

Enter your URL, and check the response headers. Look for the x-qc-pop header. If it’s there, it means your site was accessed via a QUIC.cloud PoP, your site was configured correctly, and you are good to go.

Congratulations! Your site is now using QUIC.cloud CDN 🎉

Troubleshooting¶

In rare instances, there may be a problem enabling QUIC.cloud services for your site. Here are a few reasons why that might happen.

IPs are Masked by Reverse Proxy¶

If you're using a reverse proxy (like Cloudflare), we may be having difficulty validating our QUIC.cloud server IP addresses. Learn how to fix this.

QUIC.cloud IPs are Blocked¶

In order for the WordPress plugin to communicate with QUIC.cloud, you may need to add QUIC.cloud IP addresses to your server firewall or security plugin. Please see Adding QUIC.cloud IPs to Allowlist to learn how.

QUIC.cloud Nodes are Down¶

If something has happened to the QUIC.cloud service node(s) that usually service your site, you can have the LiteSpeed Cache plugin redetect the local service nodes. Press the QUIC.cloud logo in the top right corner of the Current Cloud Nodes in Service box.

Security Plugin is Blocking Access¶

Some plugins, like Password Protected, can block access to your WordPress REST API. Check the plugin's settings, and look for some way to allow REST API access. In Password Protected, this can be found in the General tab, in the Protected Permissions setting. If you can't find such a setting in the plugin you are using, then you will need to disable the security plugin. QUIC.cloud services cannot work properly without REST API access.

REST API Issue¶

If it isn't a plugin blocking access to your WordPress REST API, it's possible the API itself is not working properly. See Solving WordPress REST API Issues for more information.

Something Else¶

If none of the above scenarios apply, please submit a ticket. We'll be happy to help you pair LiteSpeed Cache and QUIC.cloud.
