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](https://forum.legato.io/t/name-resolution-fails-after-a-few-days-weeks/4599/2). 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
