Question about offline ,please help

English is not my native language, so i will describe as much as i can.

I have an Synology NAS running DSM 7.0.1-42218 . It can’t connect to the ZT network.It just gets stuck at:
REQUESTING_CONFIGURATION PRIVATE ztyxax46bt
and I have done this :
1.My synology was configured according to official documents(Synology NAS | ZeroTier Documentation.
2.Synology Quickconnect was disabled.
3.My accounts has administrative rights.
4.l already tried to reinstall ZeroTier, tried lastest version and v1.8.1. I also turned off the firewall .
5.My computer was in the same network and ZT on my computer works well.
6. I tried remove identify.* at /var/lib/zerotier-one then restart the app,it not worked.

but this didn’t fix the issue. Any help solving this would be greatly appreciated!

Is the NAS showing up in your ZT dashboard? Have you accepted/authorized it there?
