Atlassian Stash SSL certificate renewal issue

[Jaiwardhan Puri]

So we have a self-hosted version of Atlassian BitBucket running on Ubuntu server which holds the code repository. We use a SSL certificate from DigiCert . Every year we renew the certificate which has never caused issues. However this time most of the developers are getting the following error when pushing and pulling code from GIT after the certificate was renewed

fatal: unable to access : SSL certificate problem: unable to get local issuer certificate

All searches online point to this error when you 're using a self-signed or internal PKI certificate. We are totally stumped on why a certificate issued by a public authority like DigiCert is getting this error . Any help on this would be highly appreciated.

DigiCert uses intermediate keys to sign CSRs, and they'll usually send the corrrsponding intermediate certificate(s) back with the new cert. Did you receive that, either on its own or in a bundle with your certificate?

[Jaiwardhan Puri]

It was part of a bundle which includes the root CA , Issuing CA and the actual certificate.  We have always received the same bundle. If we access the Stash website , we see no issues with the certificate and all web browsers seem happy with it. Also we have verified that the root CA and the issuing CA are there in the servers certificate store.
