Add a custom certificate for Code Suggestions

• Introduced in GitLab Duo 2.10.0.

GitLab Duo attempts to detect trusted root certificates without configuration on your part. If needed, configure your JetBrains IDE to allow the GitLab Duo plugin to use a custom SSL certificate when connecting to your GitLab instance.

To use a custom SSL certificate with GitLab Duo:

1. In your IDE, on the top bar, select your IDE name, then select Settings.
2. On the left sidebar, expand Tools, then select GitLab Duo.
3. Under Connection, enter the URL to GitLab instance.
4. To verify your connection, select Verify setup.
5. Select OK or Save.

If your IDE detects a non-trusted SSL certificate:

1. The GitLab Duo plugin displays a confirmation dialog.
2. Review the SSL certificate details shown.
   • Confirm the certificate details match the certificate shown when you connect to GitLab in your browser.
3. If the certificate matches your expectations, select Accept.

To review certificates you've already accepted:

1. In your IDE, on the top bar, select your IDE name, then select Settings.
2. On the left sidebar, select Tools > Server Certificates.
3. Select Server Certificates.
4. Select a certificate to view it.

2. On the left sidebar, expand Tools, then select GitLab Duo.
