I realise that there are many similar issues but I have NOT been unable to find a solution to the problem lots of discussion and some of it WAY over my head
The issue
select an add on > install > fail with message AddonManager.install blocked from execution , no host internet connection
I had installed a number of add ons, File Editor, Terminal & SSH, Samba Share , Studio Code Server and for one of these I had received the same failure message, my resolution to that had been to reboot my host PC and wait till the next day. On the next day the installation was fine .
Most recently I tried to install VLC got the same error no host connection reboot x n did not fix the problem I had thought it might have something to do with my location / time zone so have tried at different times but get the same result.
Much searching followed and whilst there are many words on the issue I could not find a fix that I could apply.

Integrations
HACS was installed after the above problem was discovered - no issues getting that to install
**network **
ha network info
host_internet: false
I have access to the internet from firefox browser so it seems to me that only HA does not know how to get to the internet
Resolution
I am hoping there is a very simple command that can fix the routing/domain/whatever to allow me to install add ons
