how to update an SSL Certificate when the CA Authority changes

[jabbott@EA]

I need to update my SSL Certificate, but the Authority has changed. How do you update the certificate when the CA has changed?

https://www.3cx.com/community/threads/update-renew-certificate.77468/#post-353919>
cd /var/lib/3cxpbx/Bin/nginx/conf/Instance1
chown phonesystemhonesystem YOURFQDN-crt.pem
chown phonesystemhonesystem YOURFQDN-key.pem
service nginx restart

CA changed from godaddy secure certificate authority - g2 to godaddy tls intermediate ca dv - r1v1

I have done this multiple times but I have not run into an issue. i believe the reason I am having an issue is that GoDaddy names. I have updated the SSL certifcates on ubuntu boxes and there is a place to update the CA certificate. Let me know if I need to do anything when the CA authority has changed.

The cert PEM file chain is formatted in this way

-----BEGIN CERTIFICATE-----
The FQDN cert text
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
The CA intermediate cert text
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
The CA root cert text
-----END CERTIFICATE-----

You also need to ensure that the certificate PEM files have the correct permissions after you paste the cert PEM and the key PEM files.
• Run commands:

cd /var/lib/3cxpbx/Bin/nginx/conf/Instance1/

chown phonesystemhonesystem YOURFQDN-crt.pem
chown phonesystemhonesystem YOURFQDN-key.pem

service nginx restart
