Help With Validating This Heartbeat Config

[LongBeachHXC (Forrest Weinberg)]

I am having a tough time starting a heartbeat container. I am bind mounting the config file into the path /usr/share/heartbeat/heartbeat.yml. My config file is below. I'm sure this is something simple but I haven't been able to find the error. I have even used a couple different yaml validators and it says the syntax is good. Some assistance would be greatly appreciated. Thank you.

I found it...only after I submitted this and I was able to see it on a different background.

Both ssl.key values are missing the last curly brace.

That's a tricky one, glad you found it, definitely hard to see
