Landkreis Hameln-Pyrmont isn't working anymore

[svzi]

Since a few weeks a get this error message, when I try to fetch the waste schedule for Hameln. I've also tried with the sample provided in the docs (https://github.com/mampfes/hacs_waste_collection_schedule/blob/master/doc/ics/hameln_pyrmont_de.md).

I guess that the issues started for me, when I updated home assistant (and a lot of plugins/integrations) a few weeks ago to the current version. The version before was released February 2023, when I remember correctly.

Any idea what's happening here?

I doubt that this has something to do with a update (but i might be wrong) it's some sort of ssl issue. A quick fix would be to add verify_ssl: false as parameter (this disables ssl certificate checks)

Yeah, sounds logical. And thanks for the quick fix, that had solved my issue. 👏
