are you using `localhost` as address ? then use like this `bind 127.0.1.1` — muhammed ozbilici, Aug 23 '22 at 08:18
@muhammedozbilicimy Are you refering "bind 127.0.0.1"? Where shall this command apply to ? — Lysander, Aug 23 '22 at 08:39
define in configuration file of sentinel, check this link https://rtfm.co.ua/en/redis-sentinel-bind-0-0-0-0-the-localhost-issue-and-the-announce-ip-option/ — muhammed ozbilici, Aug 23 '22 at 08:55

The solution for this one is to make sure your sentinel.conf file have the right config.

Add 127.0.0.1 redis-server in your host file. Use "redis-server" as the host value of redis for both the configurations of file("redis.windows.conf") and file("sentinel.conf").

The above solution is inferred from reading the source code file("Connection.java").

redis/clients/jedis/Connection.java:184

Some prerequisite:

windows doesn't support ping the host itself using ipv4 address but mac does.
