wsems error message : SDK: twSocket_Create: getaddrinfo() failed: [Name or service not known]"

Hello Everyone,

 

 

How's everyone doing here!  I am new to wsems and I am having some issue with starting it.  It seems the problem is "SDK: twSocket_Create: getaddrinfo() failed: [Name or service not known]".   I am not sure what name or service is this warning message referring to.   Any help would be great.  Thanks.   

P.S I am on Ubuntu 18.04 and firewall is disabled.  Internet connection to outside is fine.

Hi @KC_9903026 

 

I can see you are using port 8080 with in ws_servers. Try changing the port from 8080 to 8443

 

{
"ws_servers": [{
"host": "https://pp-2104141617f2.devportal.ptc.io",
"port": 8080
}],
