This page discusses some of the error messages encountered in Cloud SQL.
Overview
Error messages in Cloud SQL come from many sources and appear in many places. Some error messages come from the database engines themselves, some from the Cloud SQL service, some from client applications, and some are returned by calls to the Cloud SQL Admin API.
This page includes some of the most common errors seen in Cloud SQL. If you do not find the error code or message you are looking for here, you can look for source reference material here:

Failed to create subnetwork. | No more available addresses in the IP range.
Couldn't find free blocks in allocated IP ranges. Please allocate new ranges for this service provider. There are no more available addresses in the allocated IP range. Consider these possible scenarios:
For each of the above scenarios, you can elect to either expand the existing or allocate an additional IP range to the private service connection. If you're allocating a new range, take care to not create an allocation that overlaps with any existing allocations. After creating a new IP range, update the VPC peering with the following command: gcloud services vpc-peerings update \ --service=servicenetworking.googleapis.com --ranges=OLD_RESERVED_RANGE_NAME,NEW_RESERVED_RANGE_NAME \ --network=VPC_NETWORK --project=PROJECT_ID \ --force If you're expanding an existing allocation, take care to only increase the allocation range and not decrease it. For example, if the original allocation was 10.0.10.0/24, make the new allocation at least 10.0.10.0/23. In general, if starting from a /24 allocation, decrementing the /mask by 1 for each condition (additional instance type group, additional region) is a good rule of thumb. For example, if trying to create both instance type groups on the same allocation, going from /24 to /23 is enough. After expanding an existing IP range, update the vpc peering with following command: gcloud services vpc-peerings update \ --service=servicenetworking.googleapis.com --ranges=RESERVED_RANGE_NAME \ --network=VPC_NETWORK \ --project=PROJECT_ID \ --force |

Add user | If the user already exists in the database, this error can occur when you try to add them. | Check to make sure the user doesn't already exist in the database. |
Backup | If you see this during automated or manual backups, it's likely the instance disk is full. | If the temporary file size is taking up too much space, you can restart the instance to remove the file and free up the disk space. Otherwise, you might need to upgrade your instance to a larger disk size. |

|
Export | If you see this while trying to export a database to a Cloud Storage bucket, the transfer may be failing due to a bandwidth issue. | The Cloud SQL instance may be located in a different region than the Cloud Storage bucket. Reading and writing data from one continent to another involves a lot of network usage, and can cause intermittent issues like this. |
Failover (legacy) | If you're using the legacy failover configuration, this can happen when the failover replica machine is not large enough to handle the failover. | The best solution is to migrate to the current high availability configuration. Otherwise you need to update the failover replica to a larger machine. |
Failover (automatic) | An automatic failover operation can produce this error message when the service detects that the primary instance is still responsive. | There is nothing to be done in this case. The failover won't occur because it isn't needed. |
Import | The import file may contain statements which require the superuser role. | Edit the file to remove any statements which require the superuser role. |
Cloud SQL also uses some third-party binaries (for example,
mysqld
), which can generate unknown error messages. Such errors are
internal to the third-party binaries and are outside the scope of Cloud SQL.
However, sometimes a more specific error can be found in the
Cloud SQL log files at around the same
time.
Also, sometimes it is an error code that is unknown. In this case,
the complete message can be Unknown Error Code
