Is anyone else experiencing an increase in 502 Bad Request errors using the Google Cloud Identity Aware Proxy (IAP)? We have been seeing an increase in instability since 15:30 CET across the board. We use europe-west1 and europe-west4 with regional and global loadbalancers that utilize the IAP. There are no reported incidents or issues, yet we clearly observe an uptick across the board causing issues for us - whilst we have not made any changes that could clarify this ourselves.
