The matrix-nginx-proxy was reloaded on the 3rd day of the month (`15 4 3 * *`),
which makes no sense - it's too infrequently.
It's in line with the renewal time now (+5 minutes).
As described here (
https://github.com/matrix-org/synapse/issues/2438#issuecomment-327424711
), using own SSL certificates for the federation port is more fragile,
as renewing them could cause federation outages.
The recommended setup is to use the self-signed certificates generated
by Synapse.
On the 443 port (matrix-nginx-proxy) side, we still use the Let's Encrypt
certificates, which ensures API consumers work without having to trust
"our own CA".
Having done this, we also don't need to ever restart Synapse anymore,
as no new SSL certificates need to be applied there.
It's just matrix-nginx-proxy that needs to be restarted, and it doesn't
even need a full restart as an "nginx reload" does the job of swithing
to the new SSL certificates.
Moving keeps everything in the /matrix directory, so that we
wouldn't contaminate anything else on the system or risk
clashing with something else.
Also retrieving certificates separately for the Riot and Matrix domains,
which should help in multiple ways:
- allows them to be very different (completely separate base domain..)
- allows for Riot to be disabled for the playbook some time later
and still have the code not break
