hey,
I have tried to set the configuration all over again, now the status of 'repl_nodes' before the failover is:
id | type | upstream_node_id | cluster | name | conninfo | priority | active
----+---------+---------------+------------------------------------------------------------+----------+---------
1 | master | | cluster_name |node1| host=node1 dbname=repmgr port=5432 user=repmgr | 100 | t
2 | standby| 1 | cluster_name |node2| host=node2 dbname=repmgr port=5432 user=repmgr | 100 | t
3 | witness| | cluster_name |node3| host=node3 dbname=repmgr port=5499 user=repmgr | 100 | t
repmgr is started on node2 and node3 (standby and witness) now when I kill postgresmaster process I can see in the
repmgrd log the following messages:
[WARNING] connection to master has been lost, trying to recover... 60 seconds before failover decision
[WARNING] connection to master has been lost, trying to recover... 50 seconds before failover decision
[WARNING] connection to master has been lost, trying to recover... 40 seconds before failover decision
[WARNING] connection to master has been lost, trying to recover... 30 seconds before failover decision
[WARNING] connection to master has been lost, trying to recover... 20 seconds before failover decision
[WARNING] connection to master has been lost, trying to recover... 10 seconds before failover decision
and than when it tried to elect node2 to be promoted it shows the following messages:
[DEBUG] connecting to: 'host=node2 user=repmgr dbname=repmgr fallback_application_name='repmgr''
[WARNING] unable to defermmine a valid master server; waiting 10 seconds to retry...
[ERROR] unable to determine a valid master node, terminating...
[INFO] repmgrd terminating..
what am I doing wrong?

Can you send over the output of "repmgr cluster show" before and after
the failover process?
The output of SELECT * FROM repmgr_schema.repl_nodes; after the failover
(you need to change repmgr_schema with what you have configured).
Also, which version of repmgr are you running?
