Temporary database connection failures - pro plan

I have a Basic-256mb plan, the application is correctly connected to the database. It works in production, unfortunately I get 5-10 errors a day with this content:

PrismaClientKnownRequestError: Invalid prisma.offer.findMany() invocation: Can’t reach database server at xxx.frankfurt-postgres.render.com:5432 Please make sure your database server is running at xxx.frankfurt-postgres.render.com:5432
