500 Server error after upgrade 2.4.4

Hello CyberPanel Community,

We are currently unable to access the CyberPanel admin panel at:
173.212.239.71:8090/base/

All websites hosted on the server are loading correctly, but the CyberPanel admin panel is not accessible. The admin panel frequently overloads and returns a 500 Internal Server Error.

During an upgrade via SSH, the last log we received was:

[2026-01-10 21:31:38] Starting Main_Upgrade function...
[2026-01-10 21:31:38] Running: /usr/local/CyberPanel/bin/python upgrade.py v2.4.4

After this, the SSH session disconnected. We waited for over 1 hour, but the server remained down and appeared to still be processing.
After 2 hours, we manually ran the following commands:

systemctl restart lscpd
systemctl restart lsws

Despite this, the server did not respond for another 30 minutes, so we restarted the server.
After approximately 15 minutes, all websites became active again, but the CyberPanel admin panel is still not accessible.

Kindly guide us on how to resolve this issue and restore access to the CyberPanel admin panel.

Any help or guidance would be greatly appreciated.

Thank you.

After long time no reply, we rollback to 2.3 and waiting for stable version. we notice that 2.4.4 also have backup and mode security issue which is not stable version 2.4.4.

Same error here, resolved upgrading python-asgiref to a version >3.8.1 (3.11 for example).
Here’s the command i’ve used (as root):

# enter python virtualENV
source /usr/local/CyberCP/bin/activate

# Update pip
python -m pip install --upgrade pip

# Install/update asgiref
pip install "asgiref>=3.8.1,<4.0" --force-reinstall

# latest version
# pip install asgiref --upgrade --force-reinstall

After that, restart

systemctl restart lscpd

…and in my case, Cyberpanel on :8090 returns online :slight_smile:
