New downloads "Service Unavailable"

[CvH]

We are running mirrorbits not for too long but it happened already two times that new downloads are just reporting "Service Unavailable", nothing at the logs.

What I tried so far:

• rebooting whole system
• adding ?mirrorlist still reports "Service Unavailable"
• mirrorbits scan -all + reboot

:# mirrorbits version
Client:
 Version:          v0.5.1-33-gbd6d8db
 Build:            bd6d8db-master
 GoVersion:        go1.13.8
 Operating System: linux
 Architecture:     amd64
 Gomaxprocs:       1

Server:
 Version:          v0.5.1-33-gbd6d8db

 GoVersion:        go1.13.8

Any idea how to debug that problem ? I expected that new downloads get picked up automatically ?

after the new files are synced above the mirrors you still need to reboot redis + mirrorbits that the new files are found

do I need to cron those things ?
