# MongoDB Support

Generated on 10 Oct 2026

MongoDB is a source-available cross-platform document-oriented database program for high-volume storage. Classified as a NoSQL database program, MongoDB uses JSON-like documents with optional schemas.

[How do I fix the "Cannot create property _id on string" type error?](https://docs.digitalocean.com/support/how-do-i-fix-the-cannot-create-property-_id-on-string-type-error/index.html.md): Remove the _id field from your JSON data so MongoDB can automatically generate unique _id values for each document during import.

[How do I fix the "DNSHostNotFound Failed to look up service" error?](https://docs.digitalocean.com/support/how-do-i-fix-the-dnshostnotfound-failed-to-look-up-service-error/index.html.md): Use a public DNS server, such as Google’s 8.8.8.8, to resolve SRV lookups required by MongoDB’s connection string.

[How do I unblock my MongoDB database?](https://docs.digitalocean.com/support/how-do-i-unblock-my-mongodb-database/index.html.md): Increase your cluster’s disk space or delete data to unblock your MongoDB database.

[How do I fix the "Connection Refused" error when connecting to my database?](https://docs.digitalocean.com/support/how-do-i-fix-the-connection-refused-error-when-connecting-to-my-database/index.html.md): Verify the connection string, ensure correct port usage, and add your local machine to the database cluster’s trusted sources.

[How do I fix the "Connection Timed Out" error when connecting to my database?](https://docs.digitalocean.com/support/how-do-i-fix-the-connection-timed-out-error-when-connecting-to-my-database/index.html.md): Add your machine to the database cluster’s list of trusted sources in the firewall settings.

[How do I fix the "Invalid Parameters and Values" error when connecting to my database?](https://docs.digitalocean.com/support/how-do-i-fix-the-invalid-parameters-and-values-error-when-connecting-to-my-database/index.html.md): Verify the format and values in the connection string for typos or formatting errors.

[How do I fix the "No Such File or Directory" error when connecting to my database?](https://docs.digitalocean.com/support/how-do-i-fix-the-no-such-file-or-directory-error-when-connecting-to-my-database/index.html.md): Prepend your database client command to the connection string.
