ZT error when starting large transfers on openwrt

Hi all,

I recently upgraded all packages on openWRT (including zt) and I’m regularly experiencing errors when large datatransfers (remote backup) start. Device was running fine before.

Only pointer I found till now is this error in the log “daemon.err zerotier-one[1434]: connect: Operation timed out”. zt also disconnects from zerotier central when this happens.

zt version: 1.6.5 This seems to be the most recent one in opkg repo (?)

It’s a bit difficult to troubleshoot since the devices is remote I need zt to access it. Fortunately I have webcat running which restarts the devices after which it recovers.

Any ideas?
