Resolving an SSL error on the www version of a site

You may encounter an SSL error on the www version of your site even though SSL works on the non-www version of your site. This error could be due to a couple of reasons:

1. You might have generated an SSL certificate while DNS still needed to fully resolve. Removing and regenerating the SSL certificate should fix this.
2. The CNAME record may be missing. Verify the CNAME record is present, and if not, set up a CNAME record.

How to check if you have used nameservers or an A record to point your domain

To verify the CNAME record is present, first check whether you have used nameservers or an A record to point the domain. You can use a tool like DNSChecker to check: You can directly access the website of a third party DNS checker using this link: https://dnschecker.org/.

1. Enter your domain in the search field
2. Select NS from the drop down list
3. If you have used nameservers to point the domain, you’ll see four nameservers in the results. They should match the nameservers in the 10Web dashboard's 'Manage DNS' section under Hosting Services > Domains.

If you don’t see nameservers in the results, you may have used an A record to point the domain. Try another search in DNSChecker to confirm you’re using an A record:

1. Enter your domain in the search field.
2. Select A from the drop down list.
3. If you have used an A record to point the domain, you’ll see an IP address in the results. The IP address should match the IPv4 address found in the 10Web dashboard’s Datacenter & IP section under Hosting Services > Credentials.

Next, verify the CNAME record. The exact steps vary depending on whether you have used nameservers or an A record to point the domain.

How to verify a CNAME record if you have used an A record to point the domain

If you have used an A record to point your domain, please verify that the CNAME record is present. You can use DNSChecker to verify:

1. Enter your domain in the search field
2. Select CNAME from the drop down list
3. Check if you see the CNAME record.

If you are missing a CNAME record, you’ll need to add one that redirects the www-version to the non-www version of your site URL. If you have used an A record to point your domain, you can usually add the CNAME record through your domain registrar instead of the 10Web dashboard. 

How to verify a CNAME record if you have used nameservers to point a domain

If you have used nameservers to point your domain, you can view, add, or edit CNAME records in your 10Web dashboard under Hosting Services > Domains > Manage DNS. To resolve the SSL error on the www version of your site, check if there is a CNAME record present that redirects the www-version to the non-www version of your site URL. If not, set up a new CNAME record.
