Unable to install the clustersecret helm chart

[damey2011]

Before I now, I didn't have any problems using the cluster secret helm chart, but suddenly I have problems installing it.

Exception: invoke of kubernetes:helm:template failed: invocation of kubernetes:helm:template returned an error: 
failed to generate YAML for specified Helm chart: failed to pull chart: 
looks like "https://charts.clustersecret.io/" is not a valid chart repository or cannot be reached: 
Get "https://charts.clustersecret.io/index.yaml": dial tcp: lookup charts.clustersecret.io on 67.207.67.2:53: no such host

And when I do a nslookup on the domain:

Server:		8.8.8.8
Address:	8.8.8.8#53

** server can't find charts.clustersecret.io: NXDOMAIN

Is something wrong with the domain?

I understand it's not free to use domains like the clustersecret.io, maybe it can just be hosted on the github domains?
