Can't Book a Cita Previa on Windows? Fix It Now

It Works Fine — Just Not on Your PC Right Now

You sit down to book your cita previa on the Seguridad Social website and nothing happens. The page won't load, the button does nothing, or you get a cryptic error. It's not you, and it's not the website being permanently broken. These problems almost always come down to one of a handful of fixable things on your Windows PC — and most of them take under five minutes to sort out.

Let's go through them in order, starting with the most common culprits.

Step 1: Use Google Chrome or Mozilla Firefox

The Seguridad Social appointment system (sede.seg-social.gob.es) is tested and optimised for Google Chrome and Mozilla Firefox. If you're using Microsoft Edge or — please, no — Internet Explorer, switch immediately. Download Chrome or Firefox for free if you haven't already.

Also make sure your browser is fully up to date. In Chrome, click the three dots (top right) → Help → About Google Chrome. It will update automatically if needed. In Firefox, click the menu (≡) → Help → About Firefox.

Step 2: Clear Your Browser Cache and Cookies

Old, stored data can confuse government websites badly. Clearing it takes 30 seconds and fixes a surprising number of problems.

Once done, close the browser completely (all tabs), reopen it, and try the website again.

Step 3: Disable Any VPN or Proxy

Many expats on the Costa Blanca use a VPN to access UK TV or banking. The Seguridad Social site sometimes blocks or scrambles sessions when your connection appears to be coming from outside Spain. Turn your VPN off before you visit the site. You can switch it back on once you've booked.

Step 4: Check Your Date and Time Settings

This sounds odd, but if your PC's clock is wrong — even by a few minutes — secure government websites can reject your connection. Right-click the clock in your taskbar → Adjust date/time → make sure Set time automatically is switched on. Windows will sync with an internet time server and correct any drift.

Step 5: Temporarily Disable Your Antivirus Web Shield

Some antivirus programs (Avast, AVG, Bitdefender and others) have a "Web Shield" or "HTTPS scanning" feature that can interfere with secure Spanish government sites. Right-click your antivirus icon in the system tray and look for an option to pause protection for 10 minutes — just long enough to book your appointment. Re-enable it straight after.

Note: only do this on a site you trust, like the official Seguridad Social. Never disable your antivirus on unknown websites.

Step 6: Try a Different Network

Occasionally your home router's DNS settings cause issues with Spanish government domains. The quickest test: try booking on your mobile phone's 4G/5G data (not on your home Wi-Fi). If it works on the phone, the issue is with your home network settings — worth getting checked if other sites are also misbehaving.

What If None of That Works?

If you've tried every step above and the site still won't play ball, there are a couple of remaining possibilities:

One More Option: Use the Seguridad Social App

Spain's Seguridad Social has an official app called IMPORT@SS (available on Android and iPhone). For many appointment types it is actually easier to use than the website. If your PC is giving you grief, grab the app on your phone as a practical workaround while you sort the computer side of things.

If you're in the Pilar de la Horadada or Pinar de Campoverde area and your Windows PC is refusing to cooperate with government websites — or anything else — bring it in. Campoverde Repair has been untangling these problems for local residents and expats for over 30 years. No appointment needed, no jargon, no fuss.

FAQ

Why does the Seguridad Social website not work on my PC?

Most failures are caused by an outdated or incompatible browser, cached data conflicts, a VPN masking your location, or antivirus software interfering with the secure connection. Work through the steps above in order and you'll resolve the vast majority of cases.

Which browser should I use for the cita previa website?

Google Chrome or Mozilla Firefox are the most reliable choices. Make sure whichever you use is updated to its latest version before you try.

Can I book a Seguridad Social cita previa on my phone instead?

Yes. Download the free IMPORT@SS app (Android or iPhone). It handles most appointment types and is often more straightforward than the website.

My VPN is always on — do I really need to turn it off?

Yes, at least temporarily. The Seguridad Social system can block or corrupt sessions when your IP address appears to be outside Spain. Turn the VPN off, book your appointment, then turn it back on. The whole booking takes under two minutes once the site loads.
