What is tls-opts@file referring too?

[Briare0s]

I noticed you commented out chain-oauth@file in favor of tls-opts@file, resulting (I think) in the "chain-oauth@files" does not exist error" which I got when I tried to move to your new setup. What does the tls-opts@file refer too and do, and what needs to be adjusted to make things work again? Thanks in advance.

I was making connections that weren't there. For others also curious to see what tls-opts refers to, see the link in the comments.
