错误2003（HY000）：无法连接到'IPv4地址'上的MySQL服务器（10060）

Question

I have a Google Cloud SQL Instance that I have been using for some time now and connecting successfully from MySQL Workbench. However as of yesterday I can't connect using MySQL Workbench (or the command line on my laptop) and get the error:

ERROR 2003 (HY000): Can't connect to MySQL server on '207.xxx.xxx.xx' (10060)

I have done the following already:

• Authorised my laptop's IP address (found using whatismyip.com) in the Google Console.
• Assigned an IPv4 address to the database in the Google Console.
• Created new users and passwords to see if it was a user issue. But that didn't help.
• Restarted the instance, restarted my home network/laptop and got new IP addresses (and updated the authorised IP address accordingly).
• Upgraded to the latest MySQL workbench 6.3 CE but still have the issue.

The database works as my app can connect to it and accesses the data, I just can't get a remote connection from my laptop.

I am new to this and am out of ideas on how to fix it. Any help would be greatly appreciated.

Answer 1

Thanks everyone for your help. After trying all of your suggestions I found a Google group and logged the issue . Google have responded to it as follows:

David Newgas: For now try connecting from a GCE instance (including cloud shell) or using a GCE instance to proxy connections from your laptop. I have updated the dashboard with some more information (although it may take a while for you to see it due to caching) To be clear, this issue will only be affecting first generation instances.

Answer 2

I did not have enough 'points' to comment, so I'll have my say here.

I am having about exactly the same issue. About 10 days ago I connected fine to the Cloud SQL instance, and synced my db up. Yesterday I was going to push some updates etc. But I could not connect, even though I have changed nothing in respect to the database connection, except for the given IPv4.

I figured the issue was with my Django project, based on the App Engine Skeleton, so I created an issue on that project. https://github.com/GoogleCloudPlatform/appengine-django-skeleton/issues/16

Maybe/Hopefully some we get some information from there.

Answer 3

I had the same problem. By pure luck I said "Let's try to connect with my local MySQL client while the gcloud command was saying

"Whitelisting your IP for incoming connection for 5 minutes..."

and (mysql local client) worked.
