Socket error when trying to import entities

[clansdale]

I am getting a socket error when I try to import entities from file, which is strange as I am importing from a local file. Binary and xml return the same error. The app log only returns the 5 lines below. Any help is appreciated.

Maybe the firewall is blocking Binary/XML imports.

1. Can you check the value of the parameter connectionTimeout in server.xml of Tomcat?

2. Please send the Tomcat logs, we might find more relevant information there as well

For more info, you can refer to this article and this

Turns out it was an error from WSEMS on the client side that occurred after I upgraded from TW 7.4 to 8.1.
