Unable to connect with Data Loader and receiving failed to send request error
|Knowledge Article Number||000005262|
If you're getting a failed to send request error message, you'll want to check the server host Data Loader setting. We'll show you how to check this, and a few other settings that could be causing the problem.
1. Check the server host - you'll want to make sure that the server host has been set to https://login.salesforce.com or if you're using sandbox, the URL is https://test.salesforce.com.
- Proxy host
- Proxy port
- Proxy username
- Proxy password settings
4. Check network connectivity or local machine issues - Review the affected user record's login history. If the Data Loader's login attempt has been recorded, you'll want to check the login attempt status. You'll be looking for login attempts that failed due to:
- Incorrect password
- Login restrictions
- Missing a required security token
If no login attempt has been recorded, check that the correct username and server host setting is being used. Once you've confirmed that all information is correct, and you're still not seeing a login attempt recorded, check your firewall, router, switch, or other network related devices.
