+# Alteracoes de producao - 2025-12-19
+
+Registro das correcoes aplicadas na VPS para reduzir erros em logs e estabilizar certificados e Convex.
+
+## Traefik / TLS
+- ACME alterado de HTTP-01 para TLS-ALPN no servico `traefik_traefik`.
+- Reinicio do servico Traefik para aplicar a nova configuracao.
+
+## Certificados ACME
+- Remocao de certificados obsoletos no `acme.json`:
+  - `pgadmin.rever.com.br`
+  - `supa.rever.com.br`
+  - `compressor.esdrasrenan.com.br`
+- Backups gerados:
+  - `/var/lib/docker/volumes/certificados/_data/acme.json.backup-20251219011425`
+  - `/var/lib/docker/volumes/certificados/_data/acme.json.backup-` (gerado sem timestamp por comando anterior)
+
+## Convex
+- Adicionado `convex_proxy` (tinyproxy) e configurado `--convex-http-proxy` para remover warning de proxy ausente.
+- Adicionado `convex_block` (http-echo) para bloquear `POST /api/*` com `Content-Type` nao JSON (415).
+- Prioridades de roteamento ajustadas:
+  - `sistema_convex_api_json` (priority 100)
+  - `sistema_convex_api_block` (priority 50)
+  - `sistema_convex` (priority 1)
+- `RUST_LOG` ajustado para `info,common::errors=error` a fim de reduzir ruido de warnings nao criticos.
+
+## Stack / Rede
+- Criada rede `convex_internal` (overlay, internal) para trafego interno do Convex com o proxy.
+- Arquivo atualizado: `/srv/apps/sistema/stack.yml` (stack `sistema`).
+
+## Observacoes
+- A alteracao do ACME foi feita via `docker service update --args` no Traefik (nao ha stack file versionado).
