While I was trying to run 

sudo ./luaScriptResource

 in Raspberry Pi (Raspbian Jessie),  I got the following error log:

While running sudo ./wsems I was able to ping my Thingworx (I have attached the screenshot)

Can someone please help me solve this error? is it a problem with my port

[CRArko]

Hello! Thanks for posting your question in our Community.

For the error:

www.iotspace.io:80-->[WARN ] 2018-08-24 06:22:10,960 WsEmsProxy :: bindThing: Exception connecting to localhost:8001. Err: Connection refused [localhost:8001]

That may indicated a problem with talking to port 8001, check to be sure there are no active firewall blockages on that port. Also, what version of the EMS are you running?

This other post shows similar errors, and looks like it's still a work in progress.

Thanks,

-- Craig A.

Hello Craig! Thanks for your reply.

Yes. You were right. I forgot that the default port value will be taken if not specified. I specified the port name under "auto_bind". Now that error was eliminated. This is the log I get now:

[Gowresh_R]

Hello Craig! Thank you for your reply!

As you pointed out the port 8001 was an issue. Since I did not specify any port value for auto_binding, the default value of 8001 was taken. I changed it to another port and that error was solved. 

However executing the luaResource still resulted in the same errors.

My version of EMS is 5.4.0.  I tried the same with 5.4.2 but the results were the same. Somewhere in another post it was recommended to use version 5.3.2. But I was not able to get hold of that version. Could the latest version be causing these errors? With the same versions (5.4.0 and 5.4.2), I have seen people install microserver in a localhost (i.e ws_servers host as local ip address). But to my knowledge no one has installed it in a domain. Could you suggest where I will be able to get 5.3.4 version?

Thanks,

Gowresh

[Gowresh_R · Accepted solution]

My problem was solved. It was a small beginner's mistake. I failed to understand the concept that both the executable (wsems and luaResources) have to be run simultaneously. Running them fixed the issue.

Thank You.

[CRArko]

You are very welcome. Glad to hear things are working.
