 The Bastion server should now be ready for dbt Cloud to use as a tunnel into the Redshift environment.
 
-#### Intermittent connection issues
-
-<details>
-  <summary>Database Error - could not connect to server: Connection timed out</summary>
-  You will have the following components when you configure a connection to a database using an SSH tunnel: <br />
-  - An Elastic Load Balancer (ELB) or Network Load Balancing (NLB) instance.<br />
-  - A bastion host (or jump server) running the <code>sshd</code> process.<br />
-  - A Database (such as Redshift cluster)<br /><br />
-
-dbt Cloud establishes an SSH tunnel connection through the ELB or NLB to the <code>sshd</code> process. This is responsible for routing traffic to the database. When dbt initiates a job run, an SSH tunnel is created at the start of the run. If this SSH tunnel fails at any point, the job will also fail.<br />
-
-  The most common causes of tunnel failures are:<br />
-  - The SSH daemon terminates the session due to an idle timeout.<br />
-  - The ELB or NLB terminates the connection when it's idle.<br />
-
-dbt Cloud sets a value for its SSH tunnel called `ServerAliveInterval` and `ServerAliveCountMax` that polls the connection every 30 seconds and the underlying OS in our run "pods" will terminate the connection if the `sshd` process fails to respond after 300s. This will, in many cases, prevent an idle timeout entirely so long as the customer is not using ELB with a firewall-level idle timeout of less than 30 seconds. However, if the customer is using ELB and is using an Idle Connection Timeout of less than 30s, this will be insufficient to prevent tunnels from being terminated. <br />
-
-Some versions of Linux used on bastion hosts use a version of `sshd` with additional idle timeout settings `ClientAliveCountMax`. This value sets the number of client alive messages that may be sent without `sshd` receiving any messages back from the client. If this threshold is reached while client alive messages are being sent, `sshd` will disconnect the client, terminating the session. The client-alive mechanism is helpful when the client or server needs to know when a connection has become inactive. The default value is 3.<br /><br />
-
-`ClientAliveInterval`:<br />
-This value sets a timeout interval in seconds after which if no data has been received from the client, `sshd` will send a message through the encrypted channel to request a response from the client. The default is 0, indicating that these messages will not be sent to the client.<br />
-
-Using default values, tunnels could be terminated prematurely by `sshd`. To solve this problem, the `/etc/ssh/sshd_config` file on the bastion host can be configured with the following values:<br /><br />
-- `ClientAliveCountMax` 10<br />
-- `ClientAliveInterval` 30<br />
-where `ClientAliveCountMax` should be set to a non-zero value and `ClientAliveInterval` should be a value less than the ELB or NLB idle timeout value.<br />
-
-With these settings, unresponsive SSH clients will be disconnected after approximately 300 seconds, helping to prevent tunnel failures.

+## FAQs
+
+<detailsToggle alt_header="Database Error - could not connect to server: Connection timed out">
+When setting up a database connection using an SSH tunnel, you typically need these parts:
+
+- A Load Balancer (like ELB or NLB) to manage traffic.
+- A bastion host (or jump server) that runs the SSH protocol, acting as a secure entry point.
+- The database itself (such as a Redshift cluster).
+
+dbt Cloud uses an SSH tunnel to connect through the Load Balancer to the database. This tunnel is set up at the start of any dbt job run. If the tunnel drops, the job fails.
+
+Tunnel failures usually happen because:
+
+- The SSH service stops if there's no activity for too long.
+- The Load Balancer cuts off the connection if it's idle.
+- dbt Cloud tries to keep the connection alive by checking in every 30 seconds, and the system will end the connection if there's no response from the SSH service after 300 seconds. This helps avoid drops due to inactivity unless the Load Balancer's timeout is less than 30 seconds.
+
+Bastion hosts might have additional SSH settings to disconnect inactive clients after several checks without a response. By default, it checks three times.
+
+To prevent premature disconnections, you can adjust the settings on the bastion host:
+
+- `ClientAliveCountMax 10` &mdash; Allows more checks before deciding the client is inactive.
+- `ClientAliveInterval 30` &mdash; Checks for client activity every 30 seconds.
+These adjustments ensure that inactive SSH clients are disconnected after about 300 seconds, reducing the chance of tunnel failures.
