How Can I disable GB Proxy? I enabled it once, and now in UI it shows proxy.

In your SDK Connection, click Edit. Then, you should see a toggle near the bottom to enable/disable the proxy.

Also if you used back-end env vars to set up the proxy, simply remove or comment them out

@strong-mouse-55694 There is no option. (I believe as it does not make sense to enable it for backend) I commented it from code, but it's still visible in UI 😞

Assuming you're self-hosted, you'll want to check your GrowthBook app's environment variables, specifically the api server (aka back-end). In the environment variables, check to see whether something like this exists:

PROXY_ENABLED=1

If so, simply remove it. For self-hosted, the proxy either applies to all connections or none.
