When configuring a data connector to a database that requires the Data Link Server, an error occurs after clicking the Test button.
At the same time, opening the Data Link Server URL in a web browser returns Result: OK.
Error accessing Data Link Server at http://localhost:9090: connect ECONNREFUSED.
The cause for the error is that Telerik Platform is not able to resolve the provided Data Link Server URL because localhost is not a valid address. You must provide a public fully qualified domain name (FQDN) or IP address to Telerik Platform.
Ensure that the following conditions are met:
- You are entering the public server address on the data connector setup page.
- You are entering the address in the correct format. Example: http://myserver.example.com:9090 or http://203.0.113.33:9090.
