My beloved AKG 702 went silent on the right side. This is a known problem for quite some time now. AKG hopefully will replace the wires on newer headphones. My headphones are only about a year old so I could probably get it repaired but after watching a repair video I had to do this small fix myself.
and another one:
acme.sh --set-default-ca --server letsencrypt
_acme-challenge.meinsack.click. CNAME _acme-challenge.meinsack.click.madflex.de.
acme.sh --issue --dns dns_hetzner --challenge-alias meinsack.click.madflex.de -d meinsack.click
