We’re trying to setup a Topcon AGI-4 receiver with RTK capabilites, together with the TRB142, since the 2G and 3G networks will close down.
The receiver has the gyroscope and modem installed to unlock Ntrip features.
We are getting connection with the receiver, but it looks like the Ntrip server is denying the connection. I don’t really understand the error code: “server response, recv_buf:[HTTP/1.1 401 Unauthorized”.
We have correct login credentials to the Ntrip server.
I ran the Ntrip service through Putty, as seen below.

Was unable to run the ntrip client, going to retry
^A^CStop the service
NTRIP client was stopped properly
Stop the service
root@TRB142:/usr/sbin#
Does anynoe know what the reason could be here?
