🔐 How to Access ISPmanager on VPS

After installing ISPmanager, the next step is to log in through your browser. This guide explains how to open the web interface, what login credentials to use, the default port, and what to do if the panel doesn’t load. Whether you're setting up the server for the first time or managing it daily — this information will help. 💼

🌐 Default Access Address and Port

By default, ISPmanager runs on port 1500. You can access it via your browser using the IP address of your server:

https://YOUR_IP:1500

For example, if your server’s IP is 203.0.113.15, access the panel via: https://203.0.113.15:1500

🔑 Login Credentials

• 👤 Username: root or a custom user created during setup;
• 🔒 Password: set manually or displayed in the installation output;
• 📍 Domain: you can use your server’s IP or a linked domain name.

We recommend linking a domain and installing an SSL certificate via the built-in Let's Encrypt tool. This ensures secure login without browser warnings. 🔐

🚫 What If ISPmanager Doesn’t Open?

• ✅ Make sure port 1500 is open in the firewall (UFW, firewalld, iptables);
• ✅ Check if the ISPmanager service is running: systemctl status ispmanager;
• ✅ Try a different browser or incognito mode;
• ✅ For domain access, verify your A record (domain → VPS IP);
• ✅ If using Cloudflare, disable proxy (gray cloud icon).

🔧 Enabling HTTPS and SSL

Once logged in, you can enable SSL by going to “Interface Settings” → “Security” → “Install Let's Encrypt”. A valid domain is required for automatic certificate issuance.

🧠 Security Tips

• 📍 Change the default port (1500) to a less obvious one;
• 🔐 Enable two-factor authentication (2FA);
• ⚠️ Create a limited user account and disable root login;
• 🛡 Use Fail2Ban or CSF to block brute-force attacks;
• 📌 Restrict access to the panel by IP if not used regularly.
