linux - Can't start mongos process: Address already in use

I'm working with Debian 4.9.168 and I want to configure mongoDB replica set monitoring through google cloud, and I found the best solution is through bindplane bluemedora (currect me if I wrong).

So, I deployed my mongo replica and I need to start a mongos instance. I started it with that command:

sudo mongos --configdb rs0/:27019,:27019 --bind_ip 0.0.0.0

and I'm getting that error:

2019-06-09T14:18:07.899+0000 I CONTROL  [mongosMain] options: { net: { bindIp: "0.0.0.0" }, sharding: { configDB: "rs0/:27019,35.222.135.175:27019" } }

2019-06-09T14:18:07.900+0000 E SHARDING [mongosMain] Failed to set up listener: SocketException: Address already in use
2019-06-09T14:18:07.900+0000 I CONTROL [mongosMain] shutting down with code:48

So I checked if there's a process that uses that address, and there isn't:

netstat -tuna | grep 2701

I really appreciate any kind of help. Thank you :)
