/lms route returns "Not Found" on VPS Ubuntu 22.04

[ffrz]

I am experiencing an issue where the /lms route is not accessible on my VPS running Ubuntu 22.04. The server and Frappe LMS installation appear to be running correctly, but accessing /lms returns a "Not Found" error. The /apps route, however, is accessible and works as expected.

Steps to Reproduce:

• Deploy a fresh Ubuntu 22.04 VPS.
• Install Docker (28.3.3) and Docker Compose.
• Clone the Frappe LMS repository from GitHub.
• Set up Frappe LMS following the official Docker instructions.
• Start the Frappe LMS site.
• Access http://<VPS_IP>:<PORT>/lms in a browser.

Observed Behavior:

• /lms returns "Not Found".
• /apps works and is accessible.
• he Frappe LMS site is listed in bench as installed.

Expected Behavior:

• /lms should load the LMS frontend interface.

Environment:

• Ubuntu 22.04 LTS (VPS)
• Docker version: 28.3.3, build 980b856
• Frappe version: 15.x.x-develop (commit: bda03d6)
• LMS version: 2.33.0 (commit: f218846)

Additional Notes:

• The issue does not occur when running Frappe LMS locally on Windows 11 with ngrok.
• Tried fresh reinstall on the VPS; the problem persists.
• /apps route works, suggesting site is running but /lms route is not correctly routed.
