I’ve been able to find the misconfiguration. There is no config property
zeebe.broker.network.port in the broker configuration. I think it is currently not possible to directly change the port of the broker.
In fact, the broker uses multiple ports starting at 26500. According to the configuration template documentation you can make changes to it using a portOffset:
# If a port offset is set it will be added to all ports specified in the config
# or the default values. This is a shortcut to not always specifying every port.
# The offset will be added to the second last position of the port, as Zeebe
# requires multiple ports. As example a portOffset of 5 will increment all ports
# by 50, i.e. 26500 will become 26550 and so on.
# This setting can also be overridden using the environment variable ZEEBE_BROKER_NETWORK_PORTOFFSET.
# portOffset: 0
I recommend you remove that property from the broker config AND alter the gateway config with the following properties:
# this is the port that the broker is reachable at with portOffset=0
# should be different from zeebe.gateway.network.port
# as it is used for other communication
# we can leave this one the same
I hope this helps. Please let me know if you have any further questions.
