Good day, I am having a issue that i hope i can get some assistance with. I am attempting to setup survey solution in google cloud platform but currently getting a error message “Error during site initialization. Check application log file for details”

Tried to reinstall again. and i am getting this message.

The server is initializing.

Server initialization is in progress. Please wait…

Error during database migration. Check application log file for details

I have look through the logs and see that *****;Database=SurveySolutions",“FatalException”:“HqErrorDuringRunningMigrations”},“HResult”:-2146233088,“Message”:"Application cannot connect to database using provided connection string.

As far as I can understand application cannot connect to DB.

Are You using windows installer or Docker deployment?
