Zahra's sync pair was configured with http://dav.khodak.me. Traefik has a global HTTP->HTTPS redirect, but PROPFIND/PUT/MOVE are not followed through redirects by OkHttp — so every WebDAV operation was getting redirected and silently failing. 1072 logins, 0 actual DAV operations. Silently rewrite http:// to https:// at the provider level so users never need to reconfigure.
