Spring/Mongo Issue, Unable to connect to primary node in a replica set but able to connect to secondary

My Java Application is able to connect to two of the secondary instances of the replica set but not to the primary instance. error log below

org.springframework.dao.DataAccessResourceFailureException: Timed out after 90000 ms while waiting for a server that matches ReadPreferenceServerSelector{readPreference=primary}. Client view of cluster state is {type=REPLICA_SET, servers=[{address=mongo2:27019, type=REPLICA_SET_SECONDARY, roundTripTime=3.5 ms, state=CONNECTED}, {address=mongo3:27020, type=REPLICA_SET_SECONDARY, roundTripTime=5.5 ms, state=CONNECTED}, {address=mongo1:27018, type=UNKNOWN, state=CONNECTING}]

I am running the replicaSet using colima docker instance and following are the lis to commands I followed,

# pull the official mongo docker container
docker pull mongo:4.2
# create network
docker network create my-mongo-cluster
# create mongos
docker run -d --net my-mongo-cluster -p 27018:27018 --name mongo1 mongo:4.2 mongod --replSet rs0 --port 27018
docker run -d --net my-mongo-cluster -p 27019:27019 --name mongo2 mongo:4.2 mongod --replSet rs0 --port 27019
docker run -d --net my-mongo-cluster -p 27020:27020 --name mongo3 mongo:4.2 mongod --replSet rs0 --port 27020
# add hosts in /etc/hosts
sudo vim /etc/hosts
# add the below line
127.0.0.1       mongo1 mongo2 mongo3
# setup replica set
docker exec -it mongo1 mongo -port 27018
config={"_id":"rs0","members":[{"_id":0,"host":"mongo1:27018"},{"_id":1,"host":"mongo2:27019"},{"_id":2,"host":"mongo3:27020"}]}
rs.initiate(config)
