Hello @Dominic ,
Thank you for the outreach, and welcome to the HiveMQ Community!
Could you please clarify which broker we are looking to connect to that we are providing the certificate for? Based on the details you’ve provided regarding the certificate, it sounds like this may be a cloud broker but as the configuration for HiveMQ Cloud and other HiveMQ brokers are different, I want to be sure of this to offer the most accurate information possible.
Could you also provide the specific errors that you are encountering when attempting to use the certificate?
Additionally, here are some more resources for certificate implementation :

Best,
