Undefined index: host

[cachila]

We were working with mlab without any issues but when migrated to Azure Cosmos and replaced the MONGO_DNS env the below error appears. If I connect using DB_HOST, DB_PASS, etc another error appears.

dev.ERROR: Undefined index: host {"exception":"[object] (ErrorException(code: 0): Undefined index: host at /var/www/vendor/jenssegers/mongodb/src/Jenssegers/Mongodb/Connection.php:204)

In Connection.php line 204:
Undefined index: host

Error with DB_HOST, DB_PASS, etc:

dev.ERROR: No suitable servers found (`serverSelectionTryOnce` set): [socket timeout calling ismaster on '....mongo.cosmos.azure.com:10255']

Any help would be appreciated

I got the same problem as you.
After 1 hour to check, I discovered my project missed config MongoDB in config/database.php.
