WalkthroughRemote-access transitions now await WAN event results and track active startup attempts. The network stack returns the Nginx reload result. Settings updates stop remote access before applying WAN settings. Tests cover reload failures, overlapping requests, repeated requests, disable paths, and UPnP transitions.

Then waits for Nginx to reply.
New starts hold their place in line,
Old attempts pass quietly by.
The WAN event returns its word,
And hopping tests record the flight.

When /etc/rc.d/rc.nginx reload fails on the initial static start, NginxService.reload() returns false rather than throwing, while WanAccessEventHandler has already set wanaccess to true; the runtime state also remains STATIC without an error. Every subsequent cloud start therefore matches this predicate and skips setType(), so nginx is never retried and remote access can remain unavailable until a manual transition or restart. Track the reload outcome before considering static access reusable, or otherwise retry after failure.

Propagate failed disable reloads.
stopRemoteAccess() ignores the results from DISABLE_WAN_ACCESS. When nginx reload returns false, its caller can reset remote-access state to disabled even though nginx may still serve the previous static configuration. Apply the same acknowledgement check used by beginRemoteAccess().
Suggested fix
async stopRemoteAccess() {
- await this.eventEmitter.emitAsync(EVENTS.DISABLE_WAN_ACCESS);
+ const results: unknown[] = await this.eventEmitter.emitAsync(EVENTS.DISABLE_WAN_ACCESS);
+ if (!results.length || results.some((result) => result !== true)) {
+ throw new Error('Failed to reload nginx for Static Remote Access');
+ }

Repeated cloud start requests currently stop and restart Static Remote Access even when it is already active, causing nginx to reload every five minutes. Reuse healthy active static access while preserving timeout and request metadata; retain restarts for settings changes, disabled WAN access, recorded errors, and mode changes.
Reuse requires a confirmed successful nginx reload. Propagate the reload result through the existing WAN event handlers and await their completion. A failed reload records an error and permits the next request to retry. Each start has its own completion proof, which a stop invalidates before disabling WAN access. Stale completion cannot overwrite metadata or errors, reset newer state, or make a stopped or newer pending start reusable.
The settings writer explicitly stops access before changing configuration, so a new static WAN port still takes effect. UPnP lease creation and renewal retain their existing behavior.
Work intent: implement the directly assigned, validated report https://product.unraid.net/p/nginx-reloaded-every-5-min-by-unraid-api-remotestartremoteaccess-static-remote-access-7-3-3-api-4-37-5.
Validation: 138 Connect plugin tests pass, including 19 transition regressions using the real Nest event registration and NetworkService. Coverage includes failed reload followed by retry and reuse, missing or suppressed acknowledgements, pending starts, stale success or failure, newer starts or stops during teardown, metadata, timeout, settings, and UPnP transitions. Both API nginx service tests, the production Connect build, formatting, and git diff checks pass. The failed-reload regression reproduces the review finding against the previous PR source; strengthened concurrency regressions also failed before their fixes. Live appliance validation remains pending.
Dependency manifests and the lockfile are unchanged. Existing advisory dependency audit findings are outside this nginx fix.
Release note: Fixed unnecessary nginx reloads from repeated Static Remote Access requests.
