Conflict with "Sky Moon Light"

my OH3 in combination with Alexa has been running quite well. From Today on, when I ask Alexa “Turn on the lights in the bedroom”, she answers with “Sky moon light does not answer” in 50% of requests. The other 50% are still running well.
There are no error logs in OH3. I would consider this an Alexa-problem or an issue with the OH-skill. Is there maybe a naming/id problem with any “sky moon light” - skill?
Please note: My corresponding language with Alexa is German.
Thanks for any guidance and help and have a Merry Christmas.

It sounds more like a network issue. Can you please share your event logs when making these requests and provide your item definition?
