Subject: 503 Error: Upgrade/Install fails at WSGI-LSAPI step (404 Not Found)

Hello CyberPanel Community,

I am experiencing a persistent “503 Service Unavailable” error when trying to access my CyberPanel dashboard. I believe I have traced the issue to a failing step during the installation/upgrade process, but I am now stuck and would appreciate some help.

Server OS Version:
Ubuntu 22.04 LTS

CyberPanel Version:
I cannot access the version management page due to the 503 error. I was attempting to install/upgrade to the latest stable version using the official upgrade script, which pulled v2.4.3 .

Problem Description & Steps Taken:

1. My CyberPanel dashboard at https://<SERVER_IP>:8090 is showing a “503 Service Unavailable” error.

2. I checked the status of the core services, and both are running:

• systemctl status lscpd → active (running)

• systemctl status lsws → active (running)

3. Restarting the services with systemctl restart lscpd and systemctl restart lsws did not solve the issue.

4. I ran the official upgrade/repair script: sh <(curl … preUpgrade.sh).

5. The script fails consistently at the same point every time. Here is the error output from the script:

code Code

[2025-08-11 19:33:40] Installing WSGI-LSAPI...
tar: wsgi-lsapi-2.1.tgz: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
/usr/local/cyberpanel_upgrade.sh: line 984: cd: wsgi-lsapi-2.1: No such file or directory

6. To debug this, I tried to download the file manually. The first attempt revealed an SSL certificate issue:

To connect to open.litespeedtech.com insecurely, use `--no-check-certificate'.

7. Following the suggestion, I tried again with --no-check-certificate, but this revealed the true problem: a 404 Not Found error.

Log Files:
The CyberPanel main log (/home/cyberpanel/error-logs.txt) does not show any relevant errors, only routine SSL checks. The critical errors are all from the console output shown above.

It appears the wsgi-lsapi-2.1.tgz file is missing from the official LiteSpeed repository, which prevents the CyberPanel installation from completing, leading to the 503 error.

Could someone please confirm if this is a known issue or if the download URL in the script is outdated? Is there an alternative way to manually install this required WSGI-LSAPI component?

Thank you for your time and assistance.

I am still having this problem. Am I the only one?

nope. And you aren’t likely to get an answer from support either. I am looking to spin up a new VPS with a diffferent panel as there are no answers for this issue that is being shared here. Sorry, bro.

I stumbled across the answer. My DNS service was blocking www.litespeedtech.com

I have tail-scale installed on the server and it uses NextDNS which is more configured for my personal computers and blocks many things. Including litespeedtech.com

After allowing that the update completed.
