Possible Causes:
Solutions:
Example fix:
If you’re using Docker:
postgres
instead of localhost
if postgres
is the service name)For cloud deployments:
Test the connection independently: Use command-line tools to test the connection outside of R2R:
psql -h <host> -U <username> -d <dbname>
Check service logs: Examine logs of the service you’re trying to connect to for any error messages or access attempts.
Use connection string builders: Many database providers offer online tools to help construct valid connection strings.
If you’re still encountering issues:
Remember to never share actual passwords or sensitive information when asking for help. Always use placeholders in examples.
By following this guide, you should be able to resolve most connection string errors in your R2R deployment. If problems persist, don’t hesitate to seek help from the R2R community or support team.
