Shiftkey apt repo broken

[itiligent]

The problem

The shiftkey apt repo is recently broken.
In just the past few days running apt update gives :
Certificate verification failed: The certificate is NOT trusted. The name in the certificate does not match the expected. Could not handshake: Error in the certificate verification. [IP: 13.107.246.31 443]

It is also no longer possible to download th gpg key to set up a new apt based install. Browsing to https://apt.packages.shiftkey.dev is blocked due to certificate errors.

Release version

any

Operating system

Debian

Steps to reproduce the behavior

sudo apt update with the shiftkey repo configured
or
browse to https://apt.packages.shiftkey.dev
or
try to install the gpg key
wget -qO - https://apt.packages.shiftkey.dev/gpg.key | gpg --dearmor | sudo tee /usr/share/keyrings/shiftkey-packages.gpg > /dev/null

Same thing here, but instead of apt, its rpm for me.

Shiftkey said in #1109 (which was opened in august):

Closing as duplicate of #1062

This is working now, but I'll use that issue to do a brain-dump when I have bandwidth.

Some more info for diagnosis.

The certificate is not valid for apt.packages.shiftkey.dev.
The certificate is only valid for the following names: *.azureedge.net, *.media.microsoftstream.com, *.origin.mediaservices.windows.net, *.streaming.mediaservices.windows.net

https://apt.packages.shiftkey.dev/ubuntu

Unable to communicate securely with peer: requested domain name does not match the server’s certificate.

This has been restored. #1062 is the tracking the underlying issues (bandwidth used -> credits consumed -> services suspended)
