Guys i have just setup a brand new default install for Virtualmin GPL on a new instance of Debian 10. The VPS is on the Vultr network and i have other servers (including Virtualmin Pro) on the same network running Debian 9 and never had this issue.
the error is below
Failed to create virtual server : Failed to work out externally visible IP address
I have seen this error on these forums before but i ahve tried some of those solutions and they do not seem to work.
I went to mxtoolbox and entered a lookup for host dns and host.mydomain.com is resolving no problems, and its reverse ptr is also resolving no problems.
What could cause this on a brand new system?
