Replicas - not working

Hi,

I’m running cloudflared in docker containers, everything works great but I want to add resiliency by using a container on a different docker host - mitigating an issue with the docker service or docker host dying.

From my understanding I should be starting the 2 instances with the same tunnel token, but as soon as I start the 2nd tunnel I lose access to my application (SSH to a VM). If I try either of the containers on its own,

Am I approaching this correctly? Any suggestions?

Thanks

Missed off part of the sentence - If I run either of the containers on with the other not running it works
