UNDERSTAND THE TOOL
What is SSL Checker?
An SSL certificate encrypts traffic and proves the identity of a website. Expired or mismatched certificates trigger browser warnings.
When should you use it?
Run this check after installing SSL, moving hosting or before a certificate renewal deadline.

Trust chain
A trusted issuer and complete intermediate chain prevent browser certificate warnings.
Expiry window
Renew well before the displayed expiry date and verify the new certificate after installation.
HOSTGRABER EXPERT GUIDE
Checking more than the expiry date
A certificate can be unexpired and still fail because its hostname does not match, an intermediate certificate is missing or the chain terminates at an untrusted authority. Review identity, issuer and validity together.
HostGraber hosting includes HTTPS options, while dedicated SSL products support broader validation needs. After installation, test every public hostname and redirect path, then schedule monitoring so renewal problems are found before visitors see a warning.

COMMON QUESTIONS
SSL Checker FAQ
Practical answers from the HostGraber team.
How early should SSL be renewed?+
Automated certificates commonly renew around 30 days before expiry. Manual certificates should be scheduled with a safe operational buffer.
Why is SSL valid for one hostname but not another?+
Each hostname, including www and subdomains, must appear in the certificate subject alternative names.
Does SSL secure the website itself?+
SSL encrypts traffic and authenticates the endpoint; application updates, access controls and malware protection are still required.
