using pg_autoctl node_2 cannot bring back from maintenance mode

[m1nx4s]

Hello,
I am using pg_auto_failover postgresql version 16.7, RHEL 8.10:
monitor node
node_1
node_2
When applying config changes in node_1, enabling maintenance in node_2:
pg_autoctl enable maintenance
When configuration completed in node_1, disabling maintenance:
pg_autoctl enable maintenance
This command worked fine for 5-7 times when did changes and node_2 catchedup
node_1 TLI: LSN.
When applied the last time enable, disable maintenance it somehow frozen and
received an error when tried to comeback from maintenance mode:
Name | Node | Host:Port | TLI: LSN | Connection |
Reported State | Assigned State
-------+-------+-------------------------+------------------+--------------+---------------------+--------------------
node_1 | 1 | node_1:5432 | 4: 97/6C000110 | read-write |
single | single
node_2 | 2 | node_2:5432 | 4: 97/6BD90750 | none ! |
maintenance | catchingup

The last known: TLI: LSN was 97/6BD90338
Name | Node | Host:Port | TLI: LSN | Connection |
Reported State | Assigned State
-------+-------+-------------------------+------------------+--------------+---------------------+--------------------
node_1 | 1 | node_1:5432 | 4: 97/6BD90338 | read-write |
primary | primary
node_2 | 2 | node_2:5432 | 4: 97/6BD90338 | read-only |
secondary | secondary

This happened for me twice in 2 days after several commands when
enabled/disabled maintenance mode.

Is there any known issue why this happens randomly for node_2.
The only wait how i was able to fix it, i had to drop node_2 from monitor
node and reapply setup on node_2.
