Hello,

For the error:
   WSAEWOULDBLOCK Return code 10035: Resource temporarily unavailable.
it is returned from operations on nonblocking sockets that
cannot be completed immediately, for example recv when no data is queued
to be read from the socket. It is a nonfatal error, and the operation
should be retried later. It is normal for WSAEWOULDBLOCK to be reported
as the result from calling connect on a nonblocking SOCK_STREAM socket,
since some time must elapse for the connection to be established.

In any case, seems to be caused by the configuration of your network,
be it a failure on the DNS server, or a misconfiguration of the 'hosts'
files at your workstations that are connecting to the server, etc.

Can you check if the error is not caused because of a hostname
problem:
124562     Hostname resolution problems (DNS timeouts).

Note 500235 shows how to run NIPING:

"First start the NIPING server on computer A (e.g., the Application
Server) with the command line:

  niping -s -I 0        (the last character is zero, not the letter O)
Then start the client (e.g. on the front-end machine) with the command:
  niping -c -H <nipingsvr> [ -B <buffersize> -L <loops> -D <delay> ]"

Yes, that should be the reason.

Please check port 3250 if it open or not.

• netstat -a -n

Hi Martin,

This issue clearly states that something is blocking from your internet provider side.

Kindly check with your Internet provider and confirm that no ports are blocked for your connection.

It will be either your VPN firewall or your Internet provider problem..

Kindly check with them.

Thanks and Regards,
