SSL connection error when connecting N8N to LINE Messaging API

Resolved

TTao-yuenFREE3d ago

I repurchased a Zeabur server today and deployed N8N using a pre-made template. When testing the LINE Webhook, clicking 'Verify' results in the following error: "An SSL connection error occurred. For more information, see SSL/TLS specification of the webhook source in the Messaging API documentation."

Are there any known issues with the SSL certificates (specifically the certificate chain or TLS version compatibility) for the *.zeabur.app subdomain on Zeabur?

Additionally, is it possible to request a refund or switch to another provider? My development work is currently completely stalled.

Hello! The SSL connection error for the LINE Webhook is a known issue.

Please try the following:

Redeploy your n8n service in the Dashboard (this will trigger a re-issuance of the SSL certificate).
Wait a few minutes before verifying in the LINE Console.

If it still fails, please provide your service domain.

I have tried redeploying the n8n service and re-verifying with the LINE Console. It still shows the error message: "An SSL connection error occurred. For more information, see SSL/TLS specification of the webhook source in the Messaging API documentation."

Currently testing service domain: n8n webhook URLs: https://n8n-tao.zeabur.app/webhook/0215 LINE webhook URLs: Same as above

Thanks for bringing this to our attention! We looked into it and found that our upstream SSL provider, ZeroSSL, has a new trust chain that LINE's server does not recognize. We have implemented a hotfix to address this issue. Please generate another zeabur.app domain, and check if your LINE webhook is functioning properly now. Thank you!

If you have another domain with the same situation, please reply to this ticket (or open a new one), and we will gladly assist you in setting up the hotfix.

That's great! Thank you all 🥹 You've worked hard 🙏🙏 I just redeployed to the new zeabur.app domain + tested the LINE Console verification, and it successfully connected! 😭
