Curl did connect to relayd, and didn't send any request, because it
didn't accept certificate presented by relayd, so relayd didn't try to
pass this any further.
It looks like relayd didn't send all intermidiate certificates, thus
curl was not able to find complete trust chain, resulting in this error.
You can deal with it later, for now you can add option -k or --insecure
to curl, to ignore certificate verification.
Then you could look again in tcpdump, logs, and curl output.
Again, I think you are really making your life difficult trying to use
relayd. Relayd is supposed to be used as a load-balancer running on a
router, to split traffic between multiple servers, optionally
terminating TLS connection, but in your case there's only one server, so
no need to load-balance, and puma can listen on TLS on it's own, so no
need to terminate TLS connection.
Also it will add you a little bit of overhead, since relayd in layer7
has to accept the connection, and then relayd opens another connection
to puma.
