Miniflux: Many feeds not fetching with „dial tcp: lookup # on 127.0.0.11:53: server misbehaving“

[necrevistonnezr]

Many (not all) feeds that I know exist are not fetched with this error:

Miniflux is not able to reach this website due to a network error: Get "https://krebsonsecurity.com/feed/": dial tcp: lookup krebsonsecurity.com on 127.0.0.11:53: server misbehaving.

Googling this error led to nothing.

The config looks fine:

127.0.0.11:53 is the docker DNS service . It's unable to resolve that domain for some reason . Can you try host krebsonsecurity.com on the web terminal of the app?

I can add the feed here atleast.

Maybe restart unbound service.
