Network-Server does not JoinAccept device JoinRequest

Hi,

We noticed the same behaviour on our chirpstack deployment. Is it random or always repeatable ?
Which version do you use ? We have this issue with latest version (GB 3.13.1 / NS 3.15.0 / AS 3.17.0) ans the previous one (GB 3.12.0 / NS 3.14.0 / AS 3.16.0). The working stack without this strange issue is GB 3.11.0 / NS 3.13.0 / AS 3.14.0.

Here is the post on this forum I dropped relating our issue, without any answer for the moment : Downlink fcount equals 0 issue
Have you got something similar ?

Some other posts seem to show up some similar issues :
