AEMO's FRC Gas Hub web services need to have their server certificates updated every year with new certificates to replace the expiring one.

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
prod.frchub.net
apis.prod.marketnet.net.au
hub.marketnet.net.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.

The certificates can be downloaded from the link below: https://www.digicert.com/secure/download-certificate/0zb6n7hdvs5c84j41twxz695ft63p2m
