Hi,
I’m running a set-up with two Raspis for local file synchronization with mobile devices each. In addition, these Raspis are connected over the internet via IPv6 and I have my own discovery server with static IPs and proper A / AAAA entries. During some time in November global sync established via the discovery server isn’t working, i.e. not connected anymore, whereas local sync still works without issues. For troubleshooting I checked the communication of my discovery server behind the Apache proxy. There the clients are posting JSON data to indicate locally visible IPs. The strange thing is that only generic IPs like tcp://0.0.0.0:22000 and the local IPv4 address are included, but not the dedicated IPv6 of the particular Raspi. This obviously explains why connection between both Syncthing instances failed, but I don’t understand why the individual IPv6 IPs aren’t published anymore, without me doing any changes to the configuration?
Any hints / support appreciated Andreas
