Cannot get Unbound or PowerDNS running on Alpine Linux 3.6.2

Unbound

Dear list,

I’ve been trying to get either Unbound or PowerDNS running on Alpine Linux 3.6.2 for the past ~48 hours with no luck.

I’ve tried everything, and have posted logs from Unbound and PowerDNS, as well as some snapshots of network traffic using the “ss” alpine tool here:

https://forum.alpinelinux.org/forum/networking/no-dns-server-working-alpine-362

I’ve searched several search engines for similar issues and have found a few threads with people experiencing similar errors, but nothing that contains a fix for the problem.

Any help, any help at all, is very much appreciated!

It appears UDP packets appear to be blocked between my host and the root servers. I contacted the VPS provider and they’re looking into it, but for now Unbound’s tcp-upstream setting is a workaround.
