Login Page for Webmin/Virtualmin taking ages to show login screen

Hi All

First of all, thanks for a great piece of software. I'm busy trying out webmin/virtualmin at the moment. I have a problem in that it's taking ages to show the login screen when I go to my webmin portal page. Ex: testco.com:10000 takes forever to show the login - just spins.

I did capture a .har file from chrome inspector, however I can't see where to upload files here - assume one can't.

This is from the inspector though: https://x.x.x.x:10000/unauthenticated/css/bundle.min.css?1921999999999901 - this runs for 55 seconds https://x.x.x.x:10000/unauthenticated/css/fonts-roboto.min.css?1921999999999901 - this runs for 43 seconds

I'm not sure as to why this is taking sooooo long to show just the login page. However once in, it seems quick enough. It's just to get the login page.

Would anyone know as to where I can start looking to solve this problem?

Thanks in advance.

• extra info: I'm runining on ubuntu 18.04. even refreshing the web tab will then take about 55 seconds before it becomes active again...
