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:
- You might have generated an SSL certificate while DNS still needed to fully resolve. Removing and regenerating the SSL certificate should fix this.
- 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 DNS Checker to check:
- Enter your domain in the search field
- Select NS from the drop-down list
- If you have used nameservers to point the domain, you’ll see four nameservers in the results. They should match the nameservers in 10Web dashboard's Domains > Details section.
If you don’t see nameservers in the results, you may have used an A record to point the domain. Try another search in DNS Checker to confirm you’re using an A record:
- Enter your domain in the search field.
- Select A from the drop-down list.
- 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 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 DNS Checker to verify:
- Enter your domain in the search field
- Select CNAME from the drop-down list
- 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 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 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.
Website accessibility issues across different browsers
If a website opens successfully in Chrome but fails to load in Safari (or any other browser combination), it's likely due to an SSL certificate issued for the non-www version of the site. To rectify this, try regenerating the SSL certificate.
Troubleshooting mixed content issues after SSL Generation
If your site is accessible via HTTPS but appears distorted or shows a “Website not fully secure” message, this may be due to mixed content. Refer to this detailed guide to resolve the issue.
