| If you're receiving a `Failed ALPN` error when trying to connect the dbt Semantic Layer with the available [data integration tool](/docs/use-dbt-semantic-layer/avail-sl-integrations), it typically happens when connecting from a computer behind a corporate VPN or Proxy, such as Zscaler. | ||

| To fix this, add an SSL interception exception for the dbt Cloud domain in your settings. |
There was a problem hiding this comment.
I think adding a bit of context on why the error occurs might help users work with their IT department to figure out. Maybe something like:
The problem is due to the proxy interfering with the TLS handshake. The Semantic Layer uses gRPC/HTTP2 to connect, so if your proxy does not support this you'll need to add an exception for the dbt Cloud domain. If your proxy does support this, you'll need to make sure it's configured correctly to allow ALPN, or create an exception for the dbt Cloud domain.
