Hi,

I've a simple setup using filebeat (v7.8.0) pushing logs to redis v4.0.9 and seeing the following error in logs. Please help troubleshoot.

```auto
redis/client.go:239 Failed to RPUSH to redis list with: write tcp 10.xx.xx.xx:44538 -> 172.xx.xx.xx:6379: i/o timeout

```

Additional info:

- source is behind corporate firewall
- redis is on EC2
- redis server is contactable responding as expected, telnet test results below

```auto
Escape character is '^]'.
ping
+PONG
RPUSH l1 "hello"
:1
RPUSH l1 "world"
:2
LRANGE l1 0 -1
*2
$5
hello

```

Thanks in advance.
