Update server root ca certs/Centos 6 for OnwCloud?

Hello!

So we received some error reports with that the OwnCloud server cannot connect properly to the internet. We traced this down to that the Centos 6 server’s root ca certs is outdated and need to be updated as according to this thread:

https://central.owncloud.org/t/this-server-has-no-working-internet-connection/10921

We contacted our host (which we use for our OwnCloud servers), then replied this back to us, quote:
“The challenge is that OwnCloud did not deliver an approx certificate to centos 6. If you can find a certificate that contains OwnCloud’s own certificate, then we can try to import it”.

So how can we do this and resolve the issue?

Thanks a bunch!
