[Solved] My lemmy server just died over night without me doing anything

Woke up in the morning and my selfhosted Lemmy server was basically braindead. I installed it in a Proxmox lxct container using the ansible playbook. It spams my logs with this:
target: "lemmy_server::root_span_builder", name: "HTTP request", fields: "http.method=POST http.scheme=\"https\" http.host=lemmy.ohaa.xyz http.target=/inbox otel.kind=\"server\" request_id=8206186d-eaf9-486d-99ad-d9c5def188c8", file: "src/root_span_builder.rs", line: 16 }] }
