After updating the redis backend in 1294279, I ran puppet
2026-06-09T08:17:41.926893+00:00 registry2005 puppet-agent[1970984]: (/Stage[main]/Docker_registry/Service[docker-registry]) Triggered 'refresh' from 3 events
However the services, docker-registry-ha-jwt.service, docker-registry-swift.service, docker-registry-ml.service, docker-registry-restricted.service, were not restrarted (or they were reloaded yet ignored it)
Eventually, I restarted them manually according to the docs
