For future reference the above would be easier to follow if you did \x before the select * from pg_replication_slots;

Someone with more experience will need to comment further but to me:

restart_lsn     confirmed_flush_lsn
2E2A/1C0972E0	2E2A/1C097318

does not look like enough data was transferred before the slot stopped transmitting.
