Applies to Write-Back Server

Troubleshoot

I’m seeing a frowny face or a connection error when connecting to Write-Back, what can I do?

There are occasions where Write-Back won’t be available after you configure it. If you are facing this issue, please check the following steps for troubleshooting.

Solution

You don’t need to follow any particular order as these are some general steps to try while troubleshooting.

Step 1: Port not opened on the server/hosting service

Make sure that the port that you are using for Write-Back is opened either on the server or the hosting service if you are using one. (You can check which port you are using in the Write-Back Manager under “Advanced Configuration > Web Server”)

Step 2: Write-Back not in the same network or not reachable by the users

Make sure that you and/or your users can reach the Write-Back server by placing it on the same network or allowing your users to access it.

Write-Back is a web application, so when you are using it on Tableau it is not Tableau that is accessing it but the end-user. When they access a dashboard with Write-Back in it, they are accessing Write-Back directly, it just happens to be contained as an extension on the dashboard.

Step 3: Incorrect domain/server name

When configuring the domain field under Advanced Configuration > Web Server, make sure to use the correct server name where Write-Back is running. This is typically a DNS name or simply the server name in the network.

For example, our public demo runs under demo.writeback4t.com so what we place in the domain field is: demo.writeback4t.com

Step 4: Database driver java version

Sometimes the wrong version of the JDBC driver may be uploaded when configuring the database connection.

Write-Back supports Java 8 so please make sure that the driver that you use is also for Java 8.

Step 5: Incorrect certificate password

Providing the wrong password for the certificate under Advanced Configuration > Webserver will prevent Write-Back from starting up so please make sure to input the correct password. You also need to make sure that you password does not have accented characters or special characters on the password.
