How to Change the Portal Address on MAG (2026 Step-by-Step Guide)

To change the portal address on MAG, open Settings → System Settings → Servers → Portals, clear the existing text in the Portal 1 URL field, type your provider’s portal URL exactly as given, confirm with OK, then reboot the box. The portal address is what tells your MAG device where to pull its channel list, EPG, and video-on-demand catalog from, so getting this one field right fixes the vast majority of blank-screen and loading errors.

This guide covers the classic Stalker Portal menu path used on MAG 250/254/256/322/324, the newer Ministra-based Android menu used on MAG 410/420/520/540/544, exact remote-control button names (they differ by remote), and the specific fixes for every common error message you’ll see after entering a portal URL.

What Is a Portal Address on a MAG Box?

A portal address (also called a portal URL) is the web address your MAG box contacts every time it boots. That address points to your IPTV provider’s middleware — usually Stalker Portal on older MAG models or Ministra TV Platform on newer ones — which authenticates your device and streams back the channel list, program guide, and on-demand library. If the address is missing, mistyped, or pointed at a dead server, the box has nothing to load and sits on a blank screen or a ‘Portal loading’ spinner forever. For the full technical breakdown of how this handshake works, see our MAG portal explainer.

Your IPTV provider issues the portal URL when you activate a subscription. It typically looks like http://provider-domain.com:8080/c/, with a port number and a trailing /c/ path that most people leave out by mistake. RevoIPTV subscribers get this URL by email immediately after checkout — you can confirm the format works before committing by starting a free RevoIPTV trial.

How to Change the Portal Address on MAG (Classic Stalker Menu)

These steps apply to MAG 250, 254, 255, 256, 270, 322, 324, 349, 351, 352 and other classic Linux-based MAG boxes running Stalker Portal firmware, made by device manufacturer Infomir.

1. Power on the box. If it’s already stuck on a broken portal, unplug the Ethernet cable first, power-cycle the box, and let it boot without a network connection — this stops it from repeatedly failing to reach the bad URL and lets the menu open cleanly.
2. Press the Menu button on the remote (labeled SET or SETUP on some remote models) to open the main portal menu.
3. Select Settings and press OK.
4. Select System Settings and press OK.
5. Scroll to Servers and press OK.
6. Select Portals and press OK. You’ll see two slots: Portal 1 Name, Portal 1 URL, Portal 2 Name, Portal 2 URL.
7. Highlight Portal 1 URL and press OK to open the text field.
8. Clear any existing address completely using the remote’s Back (delete) key, then press the KB button (or select the on-screen keyboard icon) to activate text entry.
9. Type the full URL exactly as your provider gave it — including http:// or https://, the port number, and the trailing path such as /c/. Case and punctuation matter; a missing slash is the single most common cause of a failed connection.
10. Press KB again to close the keyboard, then press OK to confirm the field. Skipping this confirmation step is why many users find the old URL is still there after a reboot.
11. Optionally rename the entry under Portal 1 Name (e.g., ‘RevoIPTV’) so it’s easy to identify later.
12. Reconnect the Ethernet cable if you removed it, then go to Settings → Reboot, or simply power-cycle the box, to apply the new address.

Tip: Keep a second service in reserve by filling Portal 2 URL as well. With both slots populated, the box shows a portal-selection screen at boot, and each portal still needs its own MAC address activated on that provider’s server.

Changing the Portal on Newer Android-Based MAG Models

This is the part most guides skip, and it trips up a lot of people upgrading in 2026: the newer Android-powered MAG line — MAG 410, MAG420, MAG 520, MAG 540/544 — runs a different Ministra TV Platform interface, not the classic Stalker Portal UI. The menu wording and navigation are similar but not identical:

1. From the home screen, open Settings → System settings → Servers → Portals.
2. Under Compatible model, select the closest matching set-top box model (start with the newest option, such as MAG420, and work down the list if the portal fails to load) — this setting controls which protocol version the box uses to negotiate with the server.
3. Enter the portal URL in the same format as above and confirm.
4. Reboot to apply the change.

Because these newer boxes run a different Stalker Middleware/Ministra protocol version than legacy MAG250-era firmware, some older or smaller IPTV panels don’t fully support them yet — if the portal loads on a MAG254 but not on a MAG420 with the identical URL, that mismatch (not a typo) is usually the cause. Check with your provider before assuming your entry is wrong.

Entering the Portal URL Without an On-Screen Keyboard

Typing a long URL character-by-character with a D-pad is slow. Faster options:

• USB keyboard: plug one into the MAG box’s rear USB port before opening the URL field; it’s recognized instantly and lets you type normally.
• Number-pad (T9) entry: most firmware supports multi-tap text entry using the remote’s number keys, similar to old mobile phone texting.
• Clipboard paste: on firmware 3.x and later, holding OK on the URL field can paste a saved value if you’ve loaded a configuration file from a USB stick.

Connecting Your MAG Box to Your Provider (MAC Address)

A correct portal URL alone isn’t enough — your IPTV provider must also link your box’s unique MAC address to your active subscription. Without that link, the portal loads but shows an authorization error or an empty channel list. Find yours under Settings → System Information; it’s formatted like 00:1A:79:XX:XX:XX. Our guide to finding the MAC address on a MAG box walks through every model’s exact location, and you’ll need to share it when you activate a RevoIPTV subscription plan.

Portal URL vs. M3U: Which Should You Use?

Some providers, including RevoIPTV, also offer an M3U playlist as an alternative to a Stalker/Ministra portal. The table below shows how they compare on a MAG box:

For a deeper comparison, see our breakdown of M3U URL vs. portal system, which is better for watching IPTV.

Troubleshooting Portal Address Errors on MAG

Portal loads but shows ‘Authorization failed’ or an empty channel list

The URL is correct, but your MAC address hasn’t been linked to an active subscription yet. Recheck it under Settings → System Information and send it to your provider.

Portal URL field is greyed out or won’t accept input

Some middleware locks the field to prevent tampering. Try pressing OK on the highlighted field to check for a hidden PIN prompt, or contact your provider to confirm whether the box is operator-locked.

Portal loads but channels buffer or won’t play

This is almost always a network or authentication-token issue, not the address itself. Confirm your internet connection is stable and that the date and time are set correctly — an incorrect clock breaks the authentication tokens portals rely on. For general connection and STB-blocked errors, our MAG box problems guide covers the rest.

‘SSL error’ when using an https:// portal URL

Older MAG firmware doesn’t always trust modern SSL certificates. If your provider offers an http:// version of the same URL, try that, or update your firmware via Settings → Software Update to get current certificate support.

Box boots straight into a channel without showing the portal menu

The device is in Autostart mode. Press Menu during the MAG logo screen to interrupt autostart before the portal finishes loading, then follow the steps above.

New URL reverts to the old one after rebooting

This happens when OK wasn’t pressed to confirm the text field before backing out of the menu. Repeat the entry and confirm with OK immediately after typing, before navigating away.

FAQ

Where do I find the portal URL for my MAG box?

Your IPTV provider sends it when you purchase or activate a subscription. RevoIPTV includes it in the welcome email. Never guess a URL — an incorrect one prevents the box from loading any content and can trigger repeated failed-connection attempts.

Can I use two different portals on the same MAG box?

Yes. Filling both Portal 1 URL and Portal 2 URL makes the box show a selection screen at boot. Each portal needs its own active subscription tied to your MAC address.

Do I need to reboot the MAG box after changing the portal URL?

Yes. MAG boxes only read the portal URL at startup, so the change won’t take effect until you reboot via Settings → Reboot or by unplugging and replugging power.

Why does the portal keep reverting to the old URL?

You likely pressed Back before confirming the text field with OK. Re-enter the URL and press OK immediately after typing, before leaving the field.

Is the portal address the same as the MAC address?

No. The portal address is the server URL the box connects to; the MAC address is your device’s unique identifier that the provider links to your subscription. You need both set correctly for the box to connect.

Can I change the portal address remotely without touching the MAG box?

Not from the local interface — it must be entered through the on-screen Settings menu. Some Stalker/Ministra middleware deployments let operators push a portal update remotely, but that depends entirely on your provider supporting it.
