You will need to contact your host for support.

There is nothing we can do to resolve server related issues.

Running XF on Google's infrastructure is not simple & straight forward in most cases. We moved few forums to GAE & GCC recently and found that there is many configurations that you need to do before the forum start running normally.

Please note you should have some basic knowledge of SQL and how it works before you jump in to try out following stuff.

As both of these platforms depends on Google Cloud SQL. I suggest you to go over the following help document to at least check the active process list.
