Unable to connect to the cluster. It may still be starting up, please try again in a few minutes) It has been working fine for a couple months now until today

​Hello,

Thanks for reaching out on our HiveMQ Community Forum.

Is there perhaps firewall rules blocking outgoing traffic to port 8884?  
​Is it possible to test on another computer?

Regards,  
Gil
