We have a Salesforce Community with a custom domain and SSL certificate installed.
But when I do an SSL check on the site, I get this warning:
The certificate is not trusted in all web browsers. You may need to install an Intermediate/chain certificate to link it to a trusted root certificate. You can fix this by following DigiCert's Certificate Installation Instructions for your server platform. Pay attention to the parts about Intermediate certificates.
Common name: subdomain.example.com
Valid from May 16, 2018 to May 16, 2020
Serial Number: XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
Signature Algorithm: sha256WithRSAEncryption
Issuer: RapidSSL RSA CA 2018
Obviously, I cannot install a
Intermediate/chain certificate on the Salesforce servers...
But when I asked Salesforce support for help, they told me this was a developer issue, and to ask the developer community...
Why is this happening?
How can I fix it?
NOTE: I cannot publish the actual domain name publicly, but if anyone is willing to help debug, I will share privately.
