Project access tokens rejected for container registry after upgrading to GitLab 13.7

Summary

All project access tokens have stopped working (401 denied) for pulling containers after updating to GitLab 13.7.1 from 13.6.3. Podman under Fedora CoreOS is used as client.

Steps to reproduce

For GitLab Core:

1. Open any project with the container registry feature enabled.
2. Open settings/access_tokens
3. Check read_registry
4. Attempt to log in with Podman using the selected name and generated password:

[root@foo ~]# podman login --authfile=/root/.docker/config.json gitdocker.example.com
Username: foo.bar.example.com
Password: 
Error: error logging into "gitdocker.example.com": invalid username/password

Note: Using the bot account's name instead of the token name yields the same behaviour. Both worked with GitLab 13.6. Installations where the login has worked previously show the same issue.

Example Project

Unfortunately I cannot create a project to reproduce it on GitLab.com, because the feature requires a subscription.

What is the current bug behavior?

The PAT is rejected and registry read access is denied.

What is the expected correct behavior?

The PAT should be accepted for container registry access like in GitLab 13.6.

Relevant logs and/or screenshots

Podman debug log:

DEBU[0036] Looking for TLS certificates and private keys in /etc/docker/certs.d/gitdocker.example.com 
DEBU[0036] Loading registries configuration "/etc/containers/registries.conf" 
DEBU[0036] GET https://gitdocker.example.com/v2/           
DEBU[0036] Ping https://gitdocker.example.com/v2/ status 401 
DEBU[0036] GET https://git.example.com/jwt/auth?account=foo.bar.example.com&service=container_registry 
DEBU[0036] error logging into "gitdocker.example.com": unable to retrieve auth token: invalid username/password: unauthorized: HTTP Basic: Access denied 
Error: error logging into "gitdocker.example.com": invalid username/password

In GitLab's logs I unfortunately only find an nginx entry where the /jwt/auth endpoint is shown with a 401 return value. No details seem to be logged as to why access was denied. I tried grepping by the token/bot name and timestamps.

Possible fixes

N/A. I have looked over the changelog and there is a change (!47247 (merged)) related to PATs, but nothing stands out that would cause the issue I describe here.
