Web based validator generates No Errors and error 500

SDK, web-based validator and sandbox

While testing my xml file before signing I am getting two responses. The response in green bar says “Validation complete. No Errors found”. While below the message below says “INFO: Validation done with result: Error: Request failed with status code 500”

Here is my xml :
