In other window: No Master can be determined

Tried to set as master, but it did not help.

MaxScale> set server server1 master

in logs:

2018-10-18 08:09:36   info   : (4) [cli] MaxAdmin: set server server1 master
2018-10-18 08:09:36   notice : Server changed state: server1[172.17.0.3:3306]: lost_master. [Master, Running] -> [Running]

All servers are in Running state (not as master / slave states):

Same happens also with readwritesplit.

Is it a Galera cluster or a cluster with master-slave replication?

Hi! It is not galera cluster. It is MaxScale with Master Slave Slave (M-S-S) configuration. (M-S would be enough too.) I have tried with readwritesplit and readconnroute. There may be something basic missing. Grants given incorrectly? Something else missing / not executed?
