SingleFile ingest error "Failed to wait for hot connection: Connection timeout"

Double check the port you have set

If you are running and receiving the following:

# /opt/gravwell/bin/gravwell_singlefile -block-size=1024 
-i=test-dat.txt --timestamp-override=DPKG -timezone-override=America/New_York
-clear-conns= 192.168.200.2:9404192.168.200.3:9404192.168.200.4:9404 
-tag-name=test -ingest-secret=<secret> -verbose
2020/04/21 11:55:32 Failed to wait for hot connection: Connection timeout

A common gotcha is the port number. In the above 9404 is the wrong port, 4023 is the cleartext ingest port which should resolve the issue.
