Resolving 502 Authentication Failed Errors in Usenet Clients

​A "502 Authentication Failed" error indicates that your Usenet client cannot authenticate with the server due to incorrect credentials or related issues. To resolve this, consider the following steps:​

1. Verify Username and Password: Ensure that your Usenet client is using the correct username and password. Remember that credentials are case-sensitive. If you've recently changed your password, update it in your newsreader as well. ​

2. Avoid Copy-Paste Errors: When entering credentials, typing them manually can prevent accidental inclusion of extra spaces, which may occur during copy-pasting. ​

3. Check Account Status: Log in to your Newshosting control panel to confirm that your account is active and that payments are up to date. An expired credit card or account hold can lead to authentication failures. 

4. Update Password Managers: If you use a password manager, ensure it has the updated credentials after a password reset to prevent it from autofilling outdated information. 

5. Confirm Server Settings: Verify that your Usenet client's server address and port number match those provided by Newshosting. Incorrect server settings can cause authentication errors. ​

6. Limit Concurrent Connections: Exceeding the maximum allowed simultaneous connections can trigger a 502 error. Check your Usenet provider's connection limit and adjust your client's settings accordingly. ​Newshosting's Lite plan allows up to 30 connections, and the Unlimited and XL Powerpack plans allow up to 100 connections.

7. Allow Time for Changes to Propagate: After updating your credentials, it may take up to 30 minutes for changes to take effect across all servers. ​
