Hi there, here in china.
About 20 hours ago, all the ZT clients on all openwrt routers suddenly got offline; it showed that " *REQUESTING_CONFIGURATION" in the output of listnetworks.
I captured pcap on wan interface, all packets sent to zerotier related ip addresses with destination udp port 9993 got no response, and subsequently, either failed on pinging;
I tried to start ZT client on iPhone with data traffic, it got online and assigned private ip successfully; I also tried wireless relay on openwrt from iphone hotspot, all ZT clients on openwrts got online back again.
So it seems that the ccp(chinese communist party)-controlled broadband ISP has banned all zerotier service, but telecommunication service provider has not yet.
I have also tried creating a self hosting network controller on the VPS that located far away from ccp-controlled area, and joined the network, it showed the same output as “REQUESTING_CONFIGURATION”.
I have no idea how exactly ZT client retrieves its configurations from network controller by network id, but I wonder if it is possible for ZT client to get configurations from self hosted network controller directly?
