Azure网站-ODBC驱动程序的Microsoft OLE DB提供程序错误'80004005'

Question

We are running PHP and MySQL in a MS Azure Website instance. It's been running fine. Today, without us having made any changes, it went down with this error:

Microsoft OLE DB Provider for ODBC Drivers error '80004005'

[MySQL][ODBC 5.1 Driver]Can't connect to MySQL server on 'localhost' (10061)

/include/inc_database.asp, line 49 

Here are some notes on what we've learned:

• We do not have a file in our website named /inc_database.asp
• The staging version of the site works. When we swap it into the live version, the live version doesn't work.
  • Update : it appears that the staging site works only because it doesn't use a custom domain name.
  • Update 2 : Custom domains work only with the www prefix. That is, www.saltspringstudiotour.ca works whereas saltspringstudiotour.ca doesn't.
• Restarting the website did not fix the problem.
• Is this something to do with a firewall rule?
• We are connecting to a ClearDB MySQL Database.
• The ClearDB Dashboard does not expose firewall configuration settings.

It seems that the problem is associated with using a custom domain without the www prefix.

Answer 1

The problem was our DNS settings. We had an extra CNAME. This was breaking the FWD. It had nothing to do with CleraDB.
