Awesome! This question has already 5 answers..
I got reply from vultr and they said this:
We made an adjustment on our platform, to better follow standard hostname conventions as detailed in RFC 952 and RFC 1123
In short underscores are not valid in hostnames. In order to become compliant we have removed support for these in host names.
We apologize for any inconvenience this may cause.
Now how to fix this underscores issue? Any alterations can be done by createproxy? It will be helpful alot.
