Root Cause

Depending on the proxy server in use, if the required hostnames for Box connections are not allowed, the connection using the http protocol may be redirected, resulting in an error.

 

Resolution

Ensure that your proxy server allows the hostnames described in the following article: Configuring A Firewall For Box Applications and Services

Additionally, check the http connection protocol settings to prevent redirecting to a proxy server.
