I am getting ERR_SSL_PROTOCOL_ERROR for the subdomains

Site Operators Tutor Help

I deployed in AWS and it was a smooth process until I faced an issue. I have DNS configured for all such as LMS (learn.abc.in), CMS (studio.abc.in), preview.learn.abc.in, and apps.learn.abc.in
It’s working fine for learn.abc.in and studio.abc.in but when I try to register a user it redirects to apps.learn.abc.in. I am getting the ERR_SSL_PROTOCOL_ERROR there. Is there any configuration issue with Caddy or anything else I am missing?

Tutor version is 18.1.1 (Latest)

Can anyone please help me with this issue?

What are the logs coming from the caddy container? tutor local logs -f caddy

If you configured the DNS records after Caddy was last started, then you need to restart the caddy container: tutor local restart caddy.

Thank you so much @regis :raised_hands: It worked once I restarted the caddy. Thank you so much again.

It looks like apps.learn.abc.in is missing a valid SSL certificate or Caddy isn’t properly serving it. Check Caddy’s logs and ensure your DNS, TLS settings, and certificates are correctly configured. I also get the helpful guide for the error solution at:- https://certera.com/blog/how-to-fix-err-ssl-protocol-error-in-chrome/.
I hope it works!
