The logs infrastructure currently do not ingest new logs anymore. The root cause has been identified. In the meantime, if you need to access your logs, you can SSH to your application: https://www.clever-cloud.com/doc/reference/clever-tools/ssh-access/#show-your-applications-logs
EDIT 11:00 UTC: The problem is now resolved. Some logs may have been lost for that period. We apologies for the inconvenience.
