Code Error Messages Possible Cause
10038
An operation was attempted on something that is
not a socket.
This may occasionally occur. No action is required.
10048
Only one usage of each socket address (protocol/
network address/port) is normally permitted.
All communication resources are in use. This error
is frequently reported when a video can no longer
be displayed in a Viewer layout sequence.
10050 A socket operation encountered a dead network.
Occurs when the computer recognizes that the
network is down because the router or hub closest
to the computer is powered off. Normally, this
cannot be recognized, therefore this error is rarely
reported.
10051
A socket operation was attempted to an
unreachable network.
Occurs when other network devices recognize that
the network is down because the router or hub is
powered off. Normally, this cannot be recognized,
therefore this error is rarely reported.
10054
An existing connection was forcibly closed by the
remote host.
The connection was aborted by the camera due to
a camera restart or other causes. This may occur
when the camera is restarted using the restart
button on the Setting Page provided by the camera
software. However, this rarely occurs.
10060
A connection attempt failed because the
connected party did not properly respond after a
period of time, or established connection failed
because connected host has failed to respond.
A timeout occurred in the TCP connection with the
camera. This occurs when the camera is powered
off.
10061
No connection could be made because the target
machine actively refused it.
The camera rejected the TCP connection. This
occurs when the port number is incorrect or from
another cause.
10064
A socket operation failed because the destination
host was down.
Occurs when the camera is powered off. Normally,
10060 occurs.
10065
A socket operation was attempted to an
unreachable host.
There is no route for connecting to the camera. This
may also occur when there is a failure in the
network cable connected to the computer or hub.
10091
WSAStartup cannot function at this time because
the underlying system it uses to provide network
services is currently unavailable.
There is a failure on the computer’s network
adapter.
