I’ve been scratching my head to solve the following error, but haven’t made much progress:

$   barman switch-wal --force --archive --archive-timeout 180 pg  The WAL file 0000000100000059000000FF has been closed on server 'pg' Waiting for the WAL file 0000000100000059000000FF from server 'pg' (max: 180 seconds) ERROR: The WAL file 0000000100000059000000FF has not been received in 180 seconds 

I had earlier configured barman on a throwaway VPS and everything worked fine. But when I tried replicating this on our final EC2 instance, I ran into the issue mentioned above. I have ensured the following (even though I don’t remember doing this on the VPS):

• SSH from barman => pg is working
• SSH from pg => barman is working
• All firewall rules on ‘pg’ have been disabled, temporarily

What could be the issue here?

Edit: Adding the output of barman check pg
