auth issue on log file. Incoming rtsp not work

Hello!
I have IP-cam Hikvision ds-2cd2722fwd-is. RTSP stream have url: rtsp//admin_user:password@ip_address_cam:554/Streaming/Channels/101.
But, outgoing stream not start, and in log file Nimble Streamer this notice:
created socket s=1016
V: connecting to s=1016 'ip_address_cam:554'
D: rtsp open, s=1016 url=rtsp://ip_address_cam/Streaming/Channels/101

D: shutdown client s=1016
D: failed to recv from s=1016 (errno=10058)
E: failed to recv buffer from client: 1016
D: rtsp close, s=1016
D: socket s=1016 closed

Incoming stream RTSP, codec H264 - MPEG-4 AVC (part 10) (h264).
In Ip-cam enable setting RTSP Autorisation: digest. I'm change this to dagest/basic, but it's not work too. What i'm doing not right?

As soon as I asked for help, I saw the problem.
My password ended with an @, and the delimiter is also @.
In the URL line, it was necessary to write the pts: // admin_user: **** @@ ip_address_cam: 554, etc.

rtsp: // admin_user: **** @@ ip_address_cam: 554, etc.
