‘HTTP/1.1 406 Not Acceptable’ response from API when using CURL

[niuk]

I am running curl against the API URL where I have VM-1000-HV PAN (7.0.1) and getting ‘HTTP/1.1 406 Not Acceptable’ response (see output below). The same URL works fine in the browser (just copied and pasted to Chrome), so it is correct.

$ curl -v --insecure "https://10.95.2.234/esp/restapi.esp?type=op&cmd=<show><running><resource-monitor><second></second></resource-monitor></running></show>&key=LUFRPT0wOFBSTWxOdGIvazFxRkc2b2VpZnNnTUEyc1E9QnRPY0ZGNWhMd3Rya3l6VndyZnVhUT09 ="

I've added -H "Accept: text/javascript, text/html, application/xml, */*" to curl but still the same error. At least I see Accept header set correctly in the request
