Same been having problems for a week and no help from dell. Websites don't even work, what a tech savvy company Dell is

Hi @Javier Cerrada

Thanks for sharing the error message ,and I’m really sorry you’re running into this issue.

The error you're seeing:

“The proxy server received an invalid response from an upstream server. Reason: Error reading from remote server.”

usually indicates a temporary issue with the server hosting the training content or a network-related disruption.

To help us troubleshoot faster, could you please confirm:

• The specific training or course name you're trying to access
• The platform or link you're using (e.g., Dell Learning Center, LMS)
• Whether you're accessing from a corporate network, VPN, or home setup

In the meantime, you can try:

• Clearing your browser cache
• Switching to a different browser or using incognito mode
• Disconnecting from VPN (if applicable) and retrying

Please let us know if you are still facing the issue. 

Thanks

Geeta
