This page discusses some of the error messages encountered in Cloud SQL.
OverviewError 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:

Error message Troubleshooting Allocated IP range not found in network. VPC peerings were not updated after an allocated range was modified or removed.You need to modify the private connection. Use the following command, and make sure to use the --force
argument:
gcloud services vpc-peerings update \ --network=VPC_NETWORK \ --ranges=ALLOCATED_RANGES \ --service=servicenetworking.googleapis.com \ --forceError message Troubleshooting Bad request. This message can have many causes.
Illegal Argument
is one of the most common. In this case, the request is using either the wrong argument or an invalid value for the argument. For the many other causes, the error message might contain a useful hint.
For Illegal Argument
, check the request to make sure each argument is permissible and each value for the argument is valid. For all other causes, check the log files to see if there is more information there.
You need to modify the private connection. Use the following command, and make sure to use the --force
argument:
gcloud services vpc-peerings update \ --network=VPC_NETWORK \ --ranges=ALLOCATED_RANGES \ --service=servicenetworking.googleapis.com \ --forceConstraints/sql.restrictAuthorizedNetworks. The cloning operation is blocked by the
Authorized Networks
configuration. Authorized Networks
are configured for public IP addresses in the Connectivity section of the Google Cloud console, and cloning isn't permitted due to security considerations.
Remove all Authorized Networks
entries from the Cloud SQL instance if you can. Otherwise, create a replica without any Authorized Networks
entries.
PRIMARY
. The PRIMARY
filegroup, which is the main and default filegroup in a database, has run out of space.
Use the sp_helpdb
command to get information about the database.
Consider the following solutions:
Automatic storage increase
is enabled for the database instance.ALTER DATABASE
command to enable autogrowth, if it is not already enabled, and to increase the maximum file size.DBCC OPENTRAN
and DBCC SQLPERF
commands to check for open transactions that can cause the tempdb file or the transaction log to grow.Edit the primary instance to upgrade it to a larger disk size.
Error message Troubleshooting 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 \ --forceError message Troubleshooting (gcloud.sql.connect) It seems your client does not have ipv6 connectivity and the database instance does not have an ipv4 address. You're trying to connect to your private IP instance using Cloud Shell.
Connecting from Cloud Shell to an instance with only a private IP address isn't currently supported.
Error message Troubleshooting Internal error. The project could be missing the Service Networking service account required for this feature.To repair service permissions, disable the Service Networking API
, wait five minutes and then re-enable it.
Service Networking API
isn't enabled in the project.
Enable the Service Networking API
in your project. If you see this error when you're trying to assign a private IP address to a Cloud SQL instance, and you're using a Shared VPC, you also need to enable the Service Networking API
for the host project.

Wait for the previous operation to finish before beginning another.
Operation isn't valid for this instance. This error is returned from an API call toinstances.restoreBackup
, and it means that you cannot restore from backup to an instance with a storage size (XX GB) smaller than the backup size (YY GB).
Edit the target instance to increase its storage size.
Error message Troubleshooting Quota exceeded. You reached the limit of your per-minute or daily quota. Review the quotas and limits for Cloud SQL.Request an increase to your quotas from the Google Cloud console.
Error message Troubleshooting Request is missing a valid API key. You might not have a valid service account key JSON file, or it might not be stored in the expected location.Verify that you have a valid service account key JSON file in the location stored in the GOOGLE_APPLICATION_CREDENTIALS
environment variable and that the variable points to the correct location.

.The following table shows some known cases where an Unknown Error
can occur, and lists specific remedies where applicable. However, this is not a complete list. If you don't find your case in the table, check with the public issue tracker for Cloud SQL. If you don't find the issue there, consider submitting a report, or reviewing other support options.
Quota 'INTERNAL_FORWARDING_RULES_WITH_TARGET_INSTANCE_PER_NETWORK' exceeded. Limit: 100.0 globally
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
