Cannot install/update addons

This helped, thank you!

This allowed me to install my updates. Thanks. Also I can confirm after ha jobs reset… All addon installations are working again.

This stopped working after a few days and installing new supervisor and core updates.

I do get a warning, when using nmcli commands:
Warning. nmcli (1.44.2) and NetworkManager (1.40.18) versions don't match. Restarting NewtorkManager is advised.

I restarted NetworkManager and all was good for a few days installing updates etc. Then it stopped working again. Getting the following Message when trying to install updates.
'AddonManager.update' blocked from execution, no host internet connection]

Is this a long term solution or should I restore from a back-up?

FOR A NOVICE LIKE ME HERE IS WHAT WORKED IN MY CASE

Settings > System > Network > IP6 (i Disabled)

Settings > System > Network > IP4 (edit here)
I choose static IP
Typed in desired static IP // typed in Gateway IP (router ip) // DNS 8.8.8.8
