LINE Webhook Verify persistent SSL error

Have you successfully connected a project on your platform to a LINE OA via Webhook? I've seen previous error reports regarding LINE's SSL certificate verification issues. I just ran an SSL Labs test and found that it's returning an old certificate. Can you address this?

Issue: LINE Webhook Verify persistent SSL error Domain: df-n8n.zeabur.app Host: Hetzner Singapore Dedicated Server (Server ID: server-69ceaf82...)

SSL Labs Test Results: Certificate #1 (with SNI): Normal, ZeroSSL, Trusted Certificate #2 (No SNI): Zeabur Pte. Ltd. self-signed certificate, NOT TRUSTED, Alternative names INVALID

Conclusion: When the client connects without SNI, the server returns a self-signed certificate, causing the LINE server's SSL verification to fail. Please fix the No-SNI fallback certificate configuration.

Hello, thank you for your detailed analysis. We are aware of this issue. The No-SNI fallback certificate was working correctly before, but the upstream certificate provider (ZeroSSL) updated to a new CA, which caused the current problem.

We are currently working on adapting to the new certificate. In the meantime, you can temporarily resolve the LINE Webhook SSL verification failure by binding a custom domain. Once the custom domain is set up, please update your LINE Webhook URL to use that domain.

We will provide an update once the certificate issue is resolved. Thank you for your patience.
