Check your connect string again
When you are connecting to your replica with replicaset name you have to pass all the 3 hostnames in your string

Hi @Ramachandra_Tummala,

I just tried adding all hostnames - ME_CONFIG_MONGODB_URL: mongodb://${MONGO_USERNAME}:${MONGO_PASSWORD}@mongo1:27017,mongo2:27017,mongo3:27017/?authSource=admin&replicaSet=replicaSetConfig

Anyway the startap still fails

Okay, found out the issue:

It was a missconfig with defined network. Just deleted that and added all hostnames to connectionString and everything seems to be okay from now on.

Thank you @Ramachandra_Tummala for your time and minly help!
