Lighting build failed(Open Job Null, Light data Exporting failed)


I wanna do light build, but it is always failed in my company computer.

Im already do Proxy Test but its not. and Port 5222 is opened(Firewall)

but, when i do light build, in swarm agent log,
i always see this log

[Interface:OpenJob] Error: value should not be NULL.

and i think,
light data exporting cant success.
i think this is the reason.

when i do this one in my home,
in folder C:\Users{myname}\AppData\Local\UnrealEngine\4.21\Saved\Swarm\SwarmCache\Jobs\Job-0DED04D8-4895E3C7-1262BF8A-7CFA0828
there are
UnrealLightmass and lots of lightmaps (after light build, the name of this change v1.0000000000000000000000000000000B like this)

but , when i do in my office,
this folder is always empty.
i think between Launcher(im already do this one with unreal engine with github soource) lighmass and swarm.

is there any good idea to resolve this problem?
