I have the exact same problem...and then all the entities become unavailable. But if I reload the integration, it starts working fine again....

[KitHubek]

update with entities behaviour. the same here as post before. After that error i provided at my first post, all entities are unavialable :/

[enkama]

Same exact stuff for me.

[kvj]

Is it a persistent problem? Connection issues happen from time to time, but all entities should be back online after the next successful polling (30 seconds by default)

[enkama]

I mean the connection issues happen pretty often ngl. The question is if its coming from nuki_ng or from nuki itself.

Also this comes up in the console.

The bridge unfortunately supports only one http request at a time. If multiple http requests are received, the other not processed receive the 503 response. This means that some other component is querying the bridge.

Make sure you uninstalled the official HA Nuki integration, or make sure you're not using the Nuki mobile app that could potentially query the bridge, but if it happens very often, it shouldn't be the mobile app, that you occasionally open.
