Hi,
Reset the TTL-counter on the firewall, so that the firewall does not drop the connection. So one could try changing this parameter to 300 (5 minutes).This worked !! Then you should investigate why this change was necessary.

Hi,
I' am getting the following error and this happens 5 mins after the JCO Server is started. Could not find any JCO Server property which can resolve this error? I have also tried running server by disabling the Sophos which was running in my computer(so that the firewall can be turned off) and also tried setting rdisp/keepalive to 280 but still the same issue.
Any insight would really help me.

Hi,
we did all the stuff mentioned above. Finally a network analysis showed us, that one of our providers set the MTU to 1200 instead of the standard of 1500. This interferes very badly with SAP-GUI. So check this parameter with your providers, if all the steps above do not help.
Best,
Tammo

Connection Reset by Peer (WSACONNRESET or error number 10053)
I agree, had this error serveral times on some customer systems. It´s because some network errors (Connection reset). You have to find where the Network error happens for example in the Network of customer, Network Errors in the way between (Providers) or at your local data center.
As Basis admin it´s almost unpossible to find the root cause, please ask your responsible Network Support contact.

The Windows Connection Reset by Peer (WSACONNRESET or error number 10053) indicates that the connection to a communication partner was broken for UNKOWN reasons.
Possible reasons are:

Update: I previously wrote:
If you can't tweak your firewall, you could play around with the profile parameter rdisp/keepalive, which has a standard of 1200 (20 minutes). When this value is reached, the application server sends a ni_ping to the front-end, which should answer with a ni_pong. This traffic should reset the TTL-counter on the firewall, so that the firewall does not drop the connection. So one could try changing this parameter to 300 (5 minutes). I haven't tested this, but it should work.
I now set rdisp/keepalive on all my Systems (50+) to 280, and my connections are now stable. If you have got the described symptoms, try this work around. Please note: You have to REDUCE the value, not increase it.

Solution
1.
If the dispatcher crashes, it means that the entire instance terminates. In this case, put the message under the component BC-CST-DP for further analysis.
2.
Network problems must (and can only) be analyzed and solved by the customer's network department.
See also the notes listed under 'Related notes'.
If you require help analyzing the trace, send the following information to SAP Support:

I'm dealing with some kind the same error.
When logging on to my customer from my own office using VPN I have connection.
When doing the same from home, I get the SAP Logon -screen, and entering the user id and password, after about 30 seconds, I get the message "Connection Reset by peer with same error number (10054).
I suspect therefore the problem is in my router (FritzBox 7390) , but I have no clue how to investigate this.
Thx for feedback

Hey guys ! same problem with me. I'm using SAP GUI 710. Every 5-7 minutes, i have to re-log in to SAP server. Is there any one have any permanent solution. I'm really tired to do so... I couldn't continue my work due to this error message.
Looking forward for reply ...
Thanks & Regards,

Hi Hardik
I had the same problem recently. It cropped up about two months ago, everything had been running fine previously. Here our symptoms:
We are connecting to our Demo-Systems from the Internet via a Saprouter. Between the Internet and our Saprouter we have a firewall (Fortinet Fortigate). After about 10 Minutes of inactivity, the sapgui loses the connection, we got a WSAECONNRESET error. After some testing with niping.exe, rebooting, playing around with profile parameters, saprouter-Update etc. I found out that it must have something to do with the firewall settings.
In our Fortigate firewall I had to set the TTL (Time to live or Timeout) for Port 3299 to 3600 seconds. That solved our problem. Now the firewall closes the connection after an inactivity time of 3600 seconds (= 1 hour), which is suitable for us.
If you can't tweek your firewall, you could play around with the profile parameter rdisp/keepalive, which has a standard of 1200 (20 minutes). When this value is reached, the application server sends a ni_ping to the front-end, which should answer with a ni_pong. This traffic should reset the TTL-counter on the firewall, so that the firewall does not drop the connection. So one could try changing this parameter to 300 (5 minutes). I haven't tested this, but it should work.
I hope my input helps!
Kind regards,
Dieter
Hi Dieter,
Thanks for the solution.
I faced the same problem while I was trying to connect to SAP RAC systems with Internet SAPROUTER.
As I was just testing internally, I tried turning OFF the Firewal l(which is not recommended) and make it work.
It worked. Maybe I will have to try increasing the time out as you suggested.

Hi Tutika,
Check whether you have correct entry on your SAP Logon PAD.
Check whether you have Port 3200,3300,3600 opened for your Server IP or not, i.e..
telnet (Server ip) Port number.........
Check whether you have any network break b/w desktop and server.
Cheers
