404 on all pages

[marapavelka]

Everything worked fine for me until this weekend. Now I get a 404 error on all pages except Nextcloud, even on traefik.$DOMAINNAME. Here's my traefik.yml file, but I haven't changed or edited anything. I'm using ouroboros, but in the last few days only calibre and bookstack have been updated. I added the line - "traefik.http.routers.traefik-rtr.tls=true", but it didn't help. Any ideas what could be wrong?

version: "3.9"

I am having the same issue, were you able to figure this out?

[proddy]

after reading this I thought I'd check my traefik endpoints and I'm getting the same! I'll dig deeper over the weekend and try and find what broke.
