The errors reported in the question are not related to Azure Web App itself. It could be or could not be related to the DB itself. The error is mainly for connectivity failure i.e., the application code is not able to establish connection with DB.
The first step here would be isolate the issue:
1. Is it related to DB itself? - Depending on where the DB is hosted and the type of DB (Microsoft SQL, mySql etc.), verify its status and try connecting to it using any of the tools available. For example, in the case of Microsoft Azure/SQL Server, you might use sqlcmd tool or SQL Server Management Studio can be used for this purpose.
2. Is the webApps trying to connect to the correct SQL DB? - Once you have verified that the DB is up and running, the next step would be to ensure that you web application is connecting to correct DB. The connection string used to specify this db in application will have to be checked to ensure that there are no errors in server/db/userId/Password etc.
3. Is it related to connectivity/permission - If everything is verified to be fine based on the points above, the next step would be to ensure that the web app is able to reach out to db (there are no network/permission issues). Looking at the logs on SQL Server itself could provide some insights. For example, for Microsoft SQL Server (hosted on Windows Server), in EventViewer\Application logs, you would see event 18456 if there is a login issue - which would mean that the connectivity is fine, but the authentication method used is failing. In this case, you will have to assign correct permission to the identity/userid which is being used by webApp for connecting to the SQL Server.
In case the issue is related to network itself, i.e., the requests are not even reaching out to DB, depending on where the SQL Server is hosted you can perform the following:
Verify that the server is configured to allow remote connections. For Azure SQL DB you can refer to this link, if you are always getting an error.
If this error occasionally, it could be a transient issue and this link should help you.
Check the SQL Server error log for more information about the error.
I have setup a self hosted release agent for releasing my software to an Isolated App Service. If I deploy this using the Azure App Service deployment task (V4), this works just fine. I want to use the -useCHECKSUM option but this breaks the release. I get an error stating: "Error: The remote server returned an error: (502) Bad Gateway."
I have tried google-ing for the error but I could not find any relation between the parameter and the Error. I suspect the -useCHECKSUM is using a different route to deploy the Application but I cannot find out what it is using.
More Information: Could not connect to the remote computer ("xxxxxxx") using the specified process ("Web Management Service"). This can happen if a proxy server is interrupting communication with the destination server. Disable the proxy server and try again.

When I tried to deploy my projects running on IBM MobileFirst 6.3 using JDK1.7 I am getting the following error in MobileFirst Server console in Eclipse kepler SR2:
[ERROR ] Failed to obtain JMX connection to access an MBean. There
might be a JMX configuration error: Connection refused: connect
[ATTENTION] No running mxbeans found
and also I get this error message shown in the MobileFirst console:
FWLSE3030E: The runtime "myproject" does not exist in the Worklight
administration database. The database may be corrupted.
Everything was just working fine till this error appears with all my projects .
I tried to create a new project but I get the same error each time.
I even tried to delete the MobileFirst development server and add it again but nothing is changed.

See this tech note: The Worklight Development Server times out.
Steps:
Open the Servers view.
Double-click the Worklight Development Server to open the Overview pane.
Expand the Timeouts section.
Increase the value in the Start (in seconds) field. The value that can be appropriate for your case depends on your startup environment. Consider starting with a value of 180 seconds (3 minutes).
Was able to connect to my SQL Server 2012 database using localhost with no problem storing it in the App_Data folder. My connection string was...
Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\bookingsandpreorders.mdf;Integrated Security=True
However when I hosted my site on another/remote server I got the following error:
Server Error in '/' Application.
The system cannot find the file specified
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.ComponentModel.Win32Exception: The system cannot find the file specified
I thought it may be the connection string after looking at connection strings.com so I tried...
Server=.\SQLExpress;AttachDbFilename=|DataDirectory|\bookingsandpreorders.mdf;Database=bookingsandpreorders.mdf;
However now I just get another error...
Server Error in '/' Application.

Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
I've watched and read a seemingly endless amount about this error mainly involving configuring firewall, tcp port... all of which have made no difference.
I think I've made a rookie error as I've not got much experience with SQL Server Express. any suggestions?
I hope someone can help me with this. I have differente projects (websites) in Visual Studio 2010. Today when I try to expand one of the databases in the data connections of the server explorer, I get a window with this error:

The situation occurs in ALL my projects. I suppose this happens because I installed Kaspersky 2012 yesterday. Please I need help.
May be installing Kaspersky stopped SQL Server service.
Type services.msc in run dialog box to open services panel .
Make sure SQL Server service has status as Started .
If not , right click on SQL Server and select start.
Of course this is if you are using Windows .
I think the problem is with your firewall. Here is something you can do to remove this error:
