Last time this happened I fixed it by restarting the primary. Yesterday I started a new base backup around noon and it replicated without any problems for about 12 hours. Then it just stopped and I don't see any errors in the Postgres log (primary or standby). I looked at other system logs and still don't see any problems.

If there are no errors in the log, how did you conclude that replication
has stopped working? Since you're using a hot standby, you've also setup
streaming replication in addition to the WAL archiving, correct?
