pglogical status is down

Hi team,

I am using a pglogical extension for logical replication from Aurora
PostgreSQL version 12 to Linux Community PostgreSQL 12 version. While the
replication is going on the Linux machine got rebooted and the replication
did not start again.

pylon=# select pglogical.alter_subscription_synchronize('subscription1');
alter_subscription_synchronize
--------------------------------
t
(1 row)

pylon=# SELECT subscription_name, status FROM
pglogical.show_subscription_status();
subscription_name | status
-------------------+--------
subscription1 | down
(1 row)

Can you please help me with this. Does pglogical have any support to stop
and start the replication ?

Thanks
Srinivas
