TCP connection showing 'Active connection establishment in progress' / 'closed'

Hi Wüstenräuber,

   Thanks for your reply..

   As we are using MB_REDCL block with version 3.0 and also please find the attached wireshark trace for CP card (10.18.6.13) and SCS server(10.18.6.20).

Thanks,

Vishal

Hi Wüstenräuber,

  Thanks for your valuable reply...

    I am little bit afraid to change the MB_REDCL  block, because all communication data is verified and approved by our end customer also i don't want to disturb the running connection_2 by cp2 card . I tried to reset connection by downloading connection , restart cpu by power cycle & initialize the MB_REDCL block, but nothing works.

   Please find the attached diagnostic buffer  of cp card and also i will check once from partner side once SCS vendor available on site, it could be problem from firewall, may be firewall blocking data traffic from cp1 card, is it possible?

Thanks

Hello Vishal,

Please check if the "Establish active connection" setting is disabled on one of the stations. You can check this in NetPro. The connection wont be established if both the systems have this setting activated. 

Hopefully this will solve your issue.
