MongoSocketOpenException in Spring-Boot Application

I'm trying to run my app on Docker. Problem is that when I'm running image of mongo, it works perfectly. But then I'm running myapp image which using mongo as a db, it gives com.mongodb.MongoSocketOpenException: Exception opening socket. By the way I'm creating both of them under the same network.

Exception

enter image description here

Note: when I run myapp from my local it works perfectly. Problem is just about image of my app. I can`t understand what is difference? Why dos it give this error?

First command, that run mongo image:

docker run --name=mongo --rm --network=mynet  -p 27017:27017 mongo

Second command, that run myapp image:

docker run --name=myapp --rm --network=mynet  -p 8088:8080 -e MONGO_URL=mongodb://mongo:27017 myapp
