I am trying to update from Unraid 7.0.0-rc.2 to 7.3.2 through Tools → Update OS. The Unraid Connect server check completes successfully. When I click “Continue Update on [server],” the browser is sent to:

/redirect?data=...

nginx then returns:

404 Not Found

The API appears to be running normally:

unraid-api status

version: 4.35.1+a9625ae2

status: online

The relevant files and responses are:

ls -lah /usr/local/emhttp/redirect*

/usr/local/emhttp/redirect.htm

curl -sSI http://127.0.0.1/redirect

HTTP/1.1 404 Not Found

curl -sSI http://127.0.0.1/redirect

HTTP/1.1 200 OK

Content-Type: text/html

The nginx error log shows:

open() "/usr/local/emhttp/redirect" failed (2: No such file or directory)

request: "GET /redirect HTTP/1.1"

Troubleshooting already attempted:

- Updated plugins, including Unraid Connect

- Restarted unraid-api

- Rebooted the server

- Signed out and back into Unraid Connect

- Tried the hostname, local IP address, and a private browser window

- Confirmed the SSL certificate files are present

- Confirmed /redirect.htm exists and loads normally

It appears the update handoff is requesting /redirect while the installed Connect/API package provides /redirect.htm.

What is the supported way to repair this without manually updating the flash drive? Or should I just manually update the flash drive?

Diagnostics are attached.
