High availability (HA) has been implemented for the RabbitMQ server in the EU region as of Nov. 26, 2025. 

In the event of a failure on the existing server, it will automatically fail over to a replacement server.


The domain and port will remain the same:


However, after a failure and subsequent failover, the IP addresses will change to:

  • 75.2.18.186
  • 99.83.134.175


This information may be useful if the customer encounters firewall issues related to RabbitMQ. The indication of such an issue would be that the reader can communicate with the server, but shows up as offline in the BioStar Air admin portal or app.


These IP addresses are the same as those currently used by the server API domain e-afs-api.airfob.com.
