List of update URLs and protocols

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 * 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.


I see no one was able to help here. I think this is more an end user issue than a developer issue. Try the Samsung support or the community.

Use the Samsung Members app
go to and depending on your location
either → Click on Explore Tab → Click on Community
Scroll all the way down to the bottom of the page and under support is a link to the community

Good luck
