LetsencryptException: No matching zone found.

We're getting this exception since some time (we're getting ~2k of them a day):

This happened roughly since we moved the cluster to GCP's europe-north1 region, so I suspect it's just not finding the name of the zone in some list. There's no such list in the source, so I guess it comes from the Google Cloud DNS library. I wonder if just upgrading that dependency would fix this?

That's a good bet! I don't actively maintain this at the moment, but if you'd like to try doing a dependency update (the compiler should scream at you for the things that no longer work) it shouldn't be too hard. I may find some time to look at it, too, but can't promise you when.

Thanks! I tried upgrating and opened #90, code compiles fine but I didn't manage to get the tests to compile (I'm afraid I don't understand kotlin-mockito)
