After updating CloudPanel to the latest version, I'm unable to access the login page—it keeps redirecting in an endless loop. How can I resolve this?

A redirect loop on CloudPanel's login page after an update usually indicates an issue with the session, cookies, firewall, or incorrect SSL configurations.

Here's how you can quickly fix this issue:

🔸 Step 1: Clear Browser Cache and Cookies

First, ensure it's not a browser caching issue:

• Clear your browser's cache and cookies.
• Restart your browser and retry accessing CloudPanel.

🔸 Step 2: Restart CloudPanel Service

Log in via SSH and restart CloudPanel to resolve temporary service issues:

sudo systemctl restart cloudpanel

Additionally, restart PHP-FPM to ensure backend stability:

sudo systemctl restart php8.3-fpm  # replace '8.3' with your PHP version

🔸 Step 3: Check and Fix SSL Configuration

Incorrect SSL configuration often causes redirection loops:

• Check CloudPanel SSL settings:

sudo nginx -t

• If errors are shown, review and correct your SSL configuration (certificate paths, etc.), then reload Nginx:

sudo systemctl reload nginx

• Reinstall the SSL certificate via CloudPanel CLI if necessary:

clpctl lets-encrypt:install:certificate --domainName=panel.domain.com

🔸 Step 4: Verify Permissions

Incorrect permissions after an update might cause redirect loops:

clpctl system😛ermissions:reset --directories=770 --files=660 --path=/usr/local/cloudpanel

Restart CloudPanel afterward:

sudo systemctl restart cloudpanel

🔸 Step 5: Check Firewall and IP Restrictions

Make sure your IP is not being blocked:

• Temporarily disable UFW firewall for troubleshooting:

sudo ufw disable

• If CloudPanel's Basic Authentication is enabled, consider temporarily disabling it:

clpctl cloudpanel:disable:basic-auth

🔸 Step 6: Review CloudPanel Logs

Check logs for specific errors:

tail -f /usr/local/cloudpanel/storage/logs/laravel.log

Address any errors found in the logs.
