Hi @Sumit_Singh,

Is your calling application hosted on a different port?

If yes then CORS needs to be enabled.

Please have a look at below conversation.

Enable CORS in Camunda Tomcat 7.4

Hi, I am get the following error when making camunda rest call from angular UI. XMLHttpRequest cannot load http://10.75.81.71:8888/engine-rest/task?processInstanceId=177e4846-63ae-11e6-aa7a-480fcf5b710b. No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘http://127.0.0.1:8080’ is therefore not allowed access. How to enable CORS on camunda Tomcat 7.4 server. I tried adding the CORS filter in engine-rest/web.xml file, problem is not resolved. Appreciate help…
