SAP GUI 710 disconnects after 10 minutes

[Former Member]

We're are connecting to our SAP servers which are hosted in a different country via a VPN connection. Once we establish the connection using a VPN client on the PC, we connect to SAP. After 10 minutes we lose connectivity to SAP, even though the VPN is still connected. If we establish a VPN connection and leave it connected without using it, the connection stays connected for as long as needed.

This is the error received:

Hello Rayza,

The error 'WSAEWOULDBLOCK Return code 10035:

Resource temporarily unavailable'.

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 some cases,it's 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 that 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> ]"

I hope this can assist you.

If your issue persists,please let us know.
