Error Message
Error 18: Self-signed certificate.
The certificate’s common name does not match the domain name thedigitron.com. The server is serving a self-signed certificate instead of the issued Let’s Encrypt certificate.
Other Information
Hello InfinityFree Support Team,
I’m having an issue with installing a Let’s Encrypt SSL certificate on my domain, thedigitron.com.
Hosting Information
- Domain:
thedigitron.com - Hosting Account:
if0_43387902 - Server IP:
185.27.134.219 - SSL Provider: Let’s Encrypt
Problem Description
I created a Let’s Encrypt SSL certificate for thedigitron.com, and InfinityFree successfully issued it.
However, my website still shows Not Secure when accessed through HTTPS.
In the SSL Certificates section, the certificate status shows Issued, but the installation verification section (Step 5) shows Not Found.
I also checked my domain using an external SSL checker and received these errors:
- Error 18: Self-signed certificate.
- Certificate common name does not match
thedigitron.com. - The server appears to be serving a default self-signed certificate instead of my Let’s Encrypt certificate.
DNS Configuration
My domain uses external DNS management through Railway/Name.com nameservers.
The following DNS records are configured:
| Type | Name | Value |
|---|---|---|
| A | @ | 185.27.134.219 |
| A | www | 185.27.134.219 |
| CNAME | _acme-challenge | InfinityFree ACME verification destination |
The domain resolves to the correct InfinityFree server IP.
What I Have Tried
- Successfully created a Let’s Encrypt SSL certificate.
- Added the required CNAME verification record.
- Verified that the certificate status is Issued.
- Clicked Install SSL Certificate Automatically.
- Checked the active certificate using InfinityFree and an external SSL checker.
One additional detail: I previously deleted an SSL certificate order and created a new one. I’m not sure whether this could have caused the installation problem.
My Request
Could someone please check whether the newly issued Let’s Encrypt certificate is correctly installed on my hosting account?
It appears that the hosting server is still serving a self-signed certificate instead of the issued Let’s Encrypt certificate.
Please help me identify and resolve the issue.
Thank you for your assistance!
