It is worth mentioning that Google Groups is a place for non-technical how-to questions (where you're likely to find information like service status updates and release notes, and ranging from book recommendations to creative shortcuts) [1].
Therefore, I would recommend you to consider reaching out to Stack Exchange sites [2] (e.g. Server Fault [3] or Stack Overflow [4]) where Google also participates that can help you find answers and troubleshoot problems.
If you find any indication of a GCP specific issue, you may consider reporting [5] the issue with Issue Tracker with all the details [6] (omitting PII/sensitive information). You may also file a case with the GCP Support [7] and we will be more than happy to help.
