[pgpool-general: 6245] FATAL: Add to watchdog cluster request is rejected by node "redshirt2018090300:9000"

[Sebastian Stellingwerff]

I've setup a cluster with two nodes, but I run into this problem, one of them dies with the error:

FATAL:  Add to watchdog cluster request is rejected by node "redshirt2018090300:9000"
HINT:  check the watchdog configurations.

Now I've checked the configurations, and run a diff on the two, but the only thing that differs is the hostnames.

125c125
< wd_hostname = 'redshirt2018090300'
---
> wd_hostname = 'redshirt2018091100'
157c157
< heartbeat_destination0 = 'redshirt2018091100'
---
> heartbeat_destination0 = 'redshirt2018090300'
160c160
< other_pgpool_hostname0 = 'redshirt2018091100'
---
> other_pgpool_hostname0 = 'redshirt2018090300'


Is there another way of seeing what else this could be? I already set loglevel to 3 and on verbose.

Thanks!
