Invalid domain for site key

[shacks]

Wondering if anyone can help me out, I get this error while using sikka:

This is the settings I use

"sikka": {
"captcha": {
"siteKey": "something",
"secret": "something"
},
"rateLimits": {
"perIp": 20,
"perHuman": 20,
"perSession": 20
},
"times": {
"blockIpFor": 120000,
"humanLivesUpto": 3600000
},
"onlyForHumans": true
}

Any Idea why this happens?

PS. I got new keys from google, still no luck.
