Hi @davidc thanks for your response. Agreed that this is disappointing. R17 is taking ages to be released. Nobody seems to be able to answer what is causing the bug. I to have set mine to IPV4 only and that mostly works… but I am getting a name resolution failure every few days/weeks and the app is not able to get itself out of that mode.
Strangely nslookup works from the command line, but getaddrinfo return a system error.
Don’t know where to go with that now…
Thanks,
Karl
