This is a WordPress deployment on Linux Web Apps. It was working fine until approximately 4 hours ago. Without me making any changes to my Web App, I started receiving the following error when I navigate to my Web App's URL:
"Error establishing a database connection"
Also, I get the following error when I navigate to my Web App's URL/wp-admin:
"Error establishing a database connection
This either means that the username and password information in your wp-config.php file is incorrect or that contact with the database server at 1e6cac4559f943359fba7f1acb82b568-dbserver.mysql.database.azure.com could not be established. This could mean your host’s database server is down.
- Are you sure you have the correct username and password?
- Are you sure you have typed the correct hostname?
- Are you sure the database server is running?
If you are unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress Support Forums."
I have been troubleshooting the problem through Azure Chat Support for over 3 hours now, and the Azure Chat Support agent has not been able to come up with a solution. When attempting to troubleshoot the issue, we discovered that the wp-config file appears to have been reset to a default state (e.g. no host, db name, username, or password data). Please let me know how I can fix this! Thank you.
