System.CalloutException: Unable to tunnel through proxy. Proxy returns "HTTP/1.0 404 Not Found

Hi,

 

I am working on salesforce integration with SwipeClock Online Server. I am trying to call a method of SwipeClock API but receiving following error:

System.CalloutException: Unable to tunnel through proxy. Proxy returns "HTTP/1.0 404 Not Found

 

I have white listed the following IPs in Salesforce under Setup-> Security Controls -> Network Access :

204.14.232.0/23 East Coast Data Center (set one)
204.14.237.0/24 East Coast Data Center (set two)
96.43.144.0/22  MidWest Data Centers
96.43.148.0/22  MidWest Data Centers
204.14.234.0/23 West Coast Data Center (set one)
204.14.238.0/23 West Coast Data Center (set two)
182.50.76.0/22  Japan Data Center

 

But still facing the error.

 

Pls help me. I need to resolve this issue as a high priority item.

 

Thanks,

Pragati

Hi Alex,

 

I have activated the IP ranges for all the regions in salesforce but still got the same error. So I then switched to SOAP api instead of REST.

 

Thanks,

Hi Pragati,

Once you Switched the SOAP API insted of REST , REST API is it Working
