Application installation failed

Good evening

I can no longer install add-ons
I received the message ‘AddonManager.install’ blocked from execution, no host internet connection

I changed the DNS to 8.8.8.8
Restart HA.
It still doesn’t work
If you have an idea?
Thank you for your help :thinking:

Are you running HAOS?
What versions are you running - what does this say?
Open your Home Assistant instance and show your Home Assistant version information.
