Hi Slangley,

we connected our ThingWorx to Kepware OPC data and send tags information to thingworx(using Simulator driver)

and the errors were gone. I am not sure if this is what stopped errors even after disconnecting kepware I don't see errors so I hope this is the solution.I am marking this as Solution if anyone have other queries regarding this please post it here.

I am guessing that either you had a Kepware, an Edge SDK implementation or some Mashup with GetProperty Values that was connected to a previous ThingWorx version.

Was this a clean install, or did you upgrade?

This was a clean install.yeah we have previous instance connected to kepware but we disabled all kepware connections in kepserverEX.Can you specify why this  error is present like I dont have any appkeys and industrial connections in the 8.5 as it is new and how to solve these errors? I was able to connect to kepserverEX with new appkey and Industrial Connection but these errors are still present

I can only advise on what I would do, since I did not encounter this situation.
I would try to go in Tomcat's log folder, then look at the latest access_log file to detect at least from which IP those requests come (an example in my machine is this localhost_access_log.2019-10-03.txt).
You might find out this information in the CommunicationLog.
Another way to understand where that connection comes from is by using netstat or TCP view, to see the actual TCP connection that arrives in your ThingWorx Tomcat port.
I still believe it's a process that was not killed. Try to hard kill the the Kepware process, make sure you did not have the Academic simulator open.
I hope these pointers help.
