Server unable to UP after restore

Hi Team,

I am facing error during restore of PG_BASEBACKUP , server is not going UP after restoring .
We follow below process .

1. First we take backup by command : pg_basebackup -h127.0.01 -U postgres -D /mnt/backup
2. Maintain restore_command = 'cp /var/lib/pgsql/13/data/pg_log_archive/%f %p' in postgresql.conf file .
3. Create file recovery.signal file in data directory.

But when we starting server showing error below error , can you please suggest .
