The value was read with env() inside the withMiddleware closure in
bootstrap/app.php. That closure runs when the HTTP kernel is resolved,
which is before the dotenv bootstrapper reads .env — so on every web
request env() returned null for anything set in .env, and the proxy was
never trusted. It worked when the value came from a real environment
variable, which is why the Docker compose path was fine and the manual
install described in INSTALL.md, where we tell people to put it in .env,
was not. Artisan bootstraps in the other order, so a check from the
command line reported the setting as working the whole time.
Behind a TLS-terminating proxy the consequence is not subtle. Laravel
falls back to the connecting address and the plain scheme, builds every
link and redirect with http:// while the browser is on https://, and
marks the session cookie non-secure. The browser then declines to send
that cookie to what it reads as a different, less secure origin, the
session arrives empty, and the first write fails with a 419 that reads as
"your session expired" — most often on the create-your-admin form, which
is the first thing a new install submits. Afterwards each redirect leaves
and re-enters over the wrong scheme, which is the random bounce back to
the login screen people report as flakiness.
Moved to config/trustedproxy.php, the key the framework's TrustProxies
middleware already falls back to on its own. Config files load after
dotenv, so the value is there whether it comes from .env or from the
environment.
This was also the only env() read outside config/, which means
config:cache is no longer dangerous on this application.

Three findings from one report of intermittent 502s behind Nginx Proxy
Manager, all of them ours.
Stop sending the Link: preload header. AddLinkHeadersForPreloadedAssets
copied every Vite preload into a response header, duplicating tags the
document already carried in its head — twenty on the login page. nginx
buffers a response's headers into a single block defaulting to 4 KB, so
/files, at 6060 bytes of headers, was refused with "upstream sent too big
header" and the proxy answered 502. Which pages went over depended on how
many assets they loaded, which is why it read as intermittent rather than
as a header that is always too big: the login screen fitted, the
application did not. Removing it takes /files to 1247 bytes and
/dashboard from 4544 to 1247. Nothing is lost — the browser reads the
tags in the document, and we send no 103 Early Hints.
Send nginx's logs to the container's streams. supervisord captures what
each program writes to its own stdout, but nginx opens the files named in
the package's nginx.conf as soon as it reads its config, so access and
error logs went to /var/log/nginx/ inside the container. That is where
the reason for every 502 and every 403 was written, and docker logs never
showed it — so a proxy problem presented as no logs on either side, which
is exactly how it was reported.
Document the thing neither guide covered. DOCKER.md had no reverse-proxy
section at all: no mention of proxies, of 502s, or of TRUSTED_PROXIES,
which until now was explained only in a comment in the compose example.
It gains one, including that TRUSTED_PROXIES cannot cause a 502 and is
the wrong place to dig. INSTALL.md's nginx-in-front-of-Apache path gains
the proxy_* buffer settings its fastcgi_* equivalents already had.
Reported by @denkfabrik-li (#1664), who traced it to the middleware
independently, and separately by a user running Nginx Proxy Manager who
found the too-big-header line in the proxy's own log.
Client file sharing, rebuilt from the ground up: a private area per
client, resumable uploads, folders, groups and categories, sharing with
expiry dates and download limits, comments, file versions, an activity
log, a REST API, and sixteen languages.
