Hello.
I'm trying to connect a remote computer with KepServerEX (v. 6.3) with TW Manufacturing App (v. 8.1) running in PTC cloud. I've reviewed all the need configuration from both side, but I can't get the connection between KepServer and TW, even though it is possible to access the ThingWorx Composer from KepServer computer.
From the KepServer computer, the error message is the following:

Has anyone faced this kind of issue?? Or have any suggestion to fix it?
Thanks in advance!!

Solved! Go to Solution.
Hello Steven.
Actually, the issue was caused by the Endpoint Security software. Although the software was disabled, one service couldn't be stopped. So, after the uninstalling was possible to get the connection.
Thanks a lot for your help!

Greetings @steixeira,
A similar error message sequence-- timeout of the first message immediately following a socket connection-- was observed recently in a different forum thread:
https://community.ptc.com/t5/ThingWorx-Developers/KEP-connections-issue/m-p/538768/
The solution shared by the original poster was to disable third-party Endpoint Security software. Does this recommendation, or any other suggestion contained in that thread, alleviate the connection problem you are seeing?
