Participants connecting to these endpoints or receiving requests from AEMO's FRC Gas Hub platforms and have authorisation mechanisms like certificate fingerprinting in place will notice a change in AEMO's server's certificate fingerprint and will need to update their systems accordingly.

The certificate relates to "FBS-Prod-Hub.aemo.com.au" certificate and relates to the following domains.
FBS-Prod-Hub.aemo.com.au
apis.prod.aemo.com.au
hub.aemo.com.au

Participants WILL need to update the profile that communicates with the above domains.

This will need to be done to avoid the inability to send messages to the relay.
