Expected behavior

I expect it to start

Actual behavior

It does not start. However downgrading to 1.32.3 makes it work again...

Additional info

Commenting out the tls_xxx sections also makes it start, but that is unfortunate.

Thanks for the issue!

Are there any log messages, if so could you send them?
Is this a self-signed certificate? Either way, how did you generate it?
