Attach the HAR file and HTTP Error file to the case, or use CB Vault if the file is larger than 25 MB

If the error "The network collection agent failed to start" is encountered when moving to the Network tool, refer to the Known Issues section of this guide for a solution - Legacy Microsoft Edge developer documentation - Legacy Microsoft Edge developer docs
