Copy to clipboard doesn't work

Windows Server Edition 21.3.70
copy to clipboard can be done on the server’s browser ----
but it doesn’t work on any other computer, when click on it, nothing happen.
What I can do to check with it?

This is limitation of Clipboard API

Basically, website is not allowed to access user’s machine clipboard unless it’s running over https protocol. The exception is when accessing web on localhost.

This explains why clipboard works when accessing through localhost and doesn’t when accessing remotely.

See this thread

Copy to clipboard option still non functional. Admin please look into it.
