Could not add local node to cluster, status PGRES_FATAL_ERROR: ERROR: node identity for local dsn does not match current node
DETAIL: The dsn 'dbname=jorge host=10.5.101.179' connects to a node with identity (6161869759719318325,2,16389) but the local node is (6161869759719318325,2,16385)
HINT: The node_local_dsn (or, for bdr, dsn if node_local_dsn is null) parameter must refer to the node you're running this function from
CONTEXT: SQL statement "SELECT bdr.internal_begin_join(
'bdr_group_join',
local_node_name,
CASE WHEN node_local_dsn IS NULL THEN node_external_dsn ELSE node_local_dsn END,
