Problemas para conectarme en ntrip

Tengo problemas para conectarme con mi proveedor NTRIP me aparece un mensaje que dice conectado a HTTP/1.0 401 No autorizado

I have problems connecting to my NTRIP provider I get a message that says connected to HTTP / 1.0 401 Unauthorized, the team I have is Reach RS + and I use version 2.8.0. I worked fine on 5 occasions with the connection, until I couldn’t connect. Something I notice is that it does not reach the fix, it takes more than 10 minutes to reach it and it is lost quickly.
