We’re having issues getting Samsung phones to update via a customer’s corporate internet connection (filtered on firewalls). Is anyone able to provide a list of update URLs and protocols required for updates to work? We’d noticed HTTPS requests to *.ospserver.net and some QUIC traffic.
Before anyone says, it looks like everything that hits the firewall is allowed. So it’s a bit confusing why it fails but using any old home broadband connection works ok.
Thanks for any help.
