Sometimes 502 Responses when requesting V2 API

Hello 🙂

The last 502 response we got from the V1 API was on 02.12.2025. But since migrating to the V2 API a month a ago, we are receiving 502 Bad Gateway responses. This has happened a few times now and is causing issues for us.

Here the logs we could gather for further detail:
