## Symptoms

- * DynamicID authentication fails for Remote/Mobile access.
* Before R80.X it worked fine.
* From vpnd/cvpnd log: DynamicIDSession::setState new_state -103 client_code 0 server_code 403 log_msg General HTTP error

## Cause

Check Point Gateway does not send User Agent Header during in it's GET request.  

1. How it looks like when we use curl:
