Unable to update to new release

[Volkan_Bulbul]

On raspberry pi with raspbian I can’t update to new release and getting following error.

I already added keys for it.

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 1CE2AFD36DBCCA00
sudo echo “deb Index of /packages/4.x/deb/ stable main” | sudo tee /etc/apt/sources.list.d/chirpstack.list

I think this error explains it well? It looks like your server is unable to connect to artifacts.chirpstack.io (port 443). This could be caused by a network issue or it could be a firewall.
