You can usually unblock a website in Chrome by changing its Site Settings for that specific site, clearing its stored data, or removing it from any block/restricted lists. Below are the main methods that cover most situations on desktop and mobile.

Check Chrome’s site settings (desktop)

  1. Open Chrome.
  2. Go to the website that’s blocked (or try to).
  3. Click the lock / warning / info icon to the left of the address bar.
  4. Click Site settings.
  5. In the new tab, look for any permissions set to “Block” (like JavaScript, Pop‑ups, Insecure content).
  6. Change blocked items to Allow or Ask , then reload the page.

This is the quickest way to undo per‑site blocks Chrome has stored for that domain.

Unblock via Privacy & Security (desktop)

  1. Click the three dots ⋮ in the top‑right of Chrome.
  2. Go to Settings → Privacy and security → Site settings.
  3. Scroll to Recent activity or click View permissions and data stored across sites.
  4. Find the site (search by its domain if needed).
  5. Click the trash bin to Delete & reset all permissions and data for that site.
  6. Revisit the site; it will load as if it’s your first time, with default permissions.

If Chrome previously blocked the site because of cookies, pop‑ups, or other content rules, this reset will usually unblock it.

Remove from Restricted / blocked lists (Windows)

Sometimes Windows’ Internet Options “Restricted sites” list can block Chrome:

  1. In Chrome, open Settings → Advanced (if needed) → under System , click Open proxy settings.
  2. In the Security tab of the Internet Properties window, select Restricted sites → Sites.
  3. If the website is listed, select it and click Remove , then OK.
  4. Restart Chrome and try again.

This matters mostly on Windows because Chrome can inherit system‑level restrictions.

Unblock on Chrome for Android

  1. Open the Chrome app.
  2. Visit the site that’s blocked (or type its address).
  3. Tap the three dots ⋮ → Info (i) → Permissions.
  4. Change anything set to “Block” (like JavaScript, cookies, or pop‑ups) to Allow or Ask , then reload.

If that doesn’t help:

  1. Tap ⋮ → Settings → Site settings.
  2. Tap All sites.
  3. Search for the site, tap it, then tap the trash bin → Delete & reset.
  4. Reopen the site.

This clears local data and resets permissions, which often fixes mobile‑only blocking issues.

If the network or country is blocking it

If the site is blocked by:

  • Your school/work network
  • Your router / firewall
  • Your country’s ISP / censorship

then changing Chrome settings alone may not be enough. In those cases people typically:

  • Use a different network (e.g., mobile hotspot instead of school Wi‑Fi).
  • Ask the network admin to whitelist the site (if it’s legitimate and allowed by policy).
  • Use tools like VPNs or proxies where legal and allowed by your organization’s rules to bypass geo‑ or network‑level blocks.

Always respect local laws and any acceptable‑use policies at work or school when trying to unblock a site.

TL;DR:
Start with Chrome’s Site settings for that domain, then delete & reset its stored data, and finally check Windows’ Restricted sites if you’re on a PC. If it’s still blocked, it’s likely a network‑ or country‑level restriction rather than a Chrome issue.
