Yeah I saw that.  Makes no sense.  I can Wireshark it, however even if I find the cause, I’d still have to go to Synology for resolution, which I doubt will ever get fixed.  Even if they do, I doubt it’d be any time soon.  Maybe that’s me being pessimistic, I don’t know, but I just don’t if I have the time or energy for all that!

Unless you have the willingness to search & fix whatever stupidities they do in their unorthodox use of nut... just use a sane version
