MongoDB External and Internal Connection URLs Missing Required Parameters

[anirbandasjoy]

To Reproduce

1. Deploy MongoDB using Dockploy
2. Go to MongoDB service dashboard
3. Copy the External Connection URL provided by Dockploy

Example:
mongodb://user:password@1.2.4.5:27017/database

4. Try connecting to MongoDB using the External URL
5. Connection fails
6. Copy the Internal Connection URL

Example:
mongodb://user:password@mongodb:27017/database

7. Try connecting using the Internal URL
8. Connection also fails
9. Add the following parameters to the connection string:
   ?authSource=admin&directConnection=true
10. Connection works successfully

Current vs. Expected behavior

Current Behavior

The provided MongoDB connection URLs do not work:

External:
mongodb://user:password@1.2.4.5:27017/database

Internal:
mongodb://user:password@mongodb:27017/database

Connection fails without additional parameters.

Expected Behavior

The provided URLs should work without modification.

However, currently they only work when adding:

?authSource=admin&directConnection=true

Working Examples:

External:
mongodb://user:password@1.2.4.5:27017/database/?authSource=admin&directConnection=true

Internal:
mongodb://user:password@mongodb:27017/database/?authSource=admin&directConnection=true

Hi @anirbandasjoy! I'm Dosu and I’m helping the dokploy team.

Thanks for the detailed report! I found the root cause in the codebase.

The MongoDB connection URL generation in Dokploy currently doesn't include any query parameters [1] [2]:

// External URL
`mongodb://${data?.databaseUser}:${data?.databasePassword}@${getIp}:${port}`

// Internal URL  
`mongodb://${data?.databaseUser}:${data?.databasePassword}@${data?.appName}:27017`

This matches your observation—the URLs are generated without ?authSource=admin&directConnection=true.

There's also a related discussion [3] where users confirmed that directConnection=true is required for external connections to MongoDB with Replica Sets.

Since you've indicated you'll send a PR to fix this, the relevant files to update are:

• apps/dokploy/components/dashboard/mongo/general/show-external-mongo-credentials.tsx
• apps/dokploy/components/dashboard/mongo/general/show-internal-mongo-credentials.tsx

To reply, just mention @dosu.
