Grok Not Working? How to Fix It Fast

If Grok is not working, the cause is almost always one of six things: an outage, a sign-in or subscription problem, an old app version, a weak network, a rate limit, or a region block.

This guide walks through each place Grok runs and gives you concrete steps to get it working again.

Start with the outage check at the bottom if nothing else fixes it. A server-side outage is not something you can fix from your device.

Why Is Grok Not Working? Common Causes at a Glance

Grok stops working for six main reasons, and most are quick to rule out. The fastest triage is to test Grok in a second place, such as the web after the app, to learn whether the problem is your device or the service.

A server-side outage affects everyone at once. A local problem affects only you and usually points to network, login, or app version.

Run through the list below before you reinstall anything. Reinstalling rarely helps when the real issue is a rate limit or an outage.

• Outage: xAI servers are down, so Grok fails everywhere at once.
• Sign-in or subscription: your session expired, or your plan does not cover the feature you tapped.
• App version: an outdated build breaks after a server update.
• Network: weak Wi-Fi, a VPN, or a firewall blocks the connection.
• Rate limits: you hit the message cap for your plan and must wait for the reset.
• Region: Grok is not available or is restricted in your country.

Grok Not Working on X (Twitter)

When Grok will not respond on X, first confirm your account meets the access requirements for the feature you are using. Grok access on X has historically been tied to a paid X subscription, so a free account may see the button but get no reply.

Tagging @grok on a post can also fail during heavy load or a partial outage. In that case the reply is delayed or never arrives, even though the rest of X works fine.

Region matters too. Grok on X is not offered in every country, and a VPN can trigger a block.

• Confirm your X plan includes Grok, then sign out and back in to refresh access.
• Update the X app to the latest version from the App Store or Google Play.
• Open the Grok tab directly instead of tagging @grok, which can lag under load.
• Turn off any VPN or proxy, then retry from your real region.
• Clear the X app cache, or use x.com in a browser to isolate the app.
• Wait a few minutes if you have sent many prompts; you may have hit a usage cap.

Grok Not Working in the App (iPhone and Android)

When the Grok app fails to load or answer, an outdated version is the most common cause. App updates often follow server changes, so an old build can break within days.

Login loops and blank screens usually clear after you sign out, restart the app, and sign back in. A corrupted cache causes many of these freezes.

Reinstalling is the last step, not the first. It logs you out and clears local data, so try the lighter fixes first.

• Update the Grok app in the App Store (iPhone) or Google Play (Android).
• Force-close the app and reopen it to clear a stuck session.
• Sign out, restart your phone, then sign back in.
• On Android, clear the app cache in Settings, Apps, Grok, Storage.
• On iPhone, offload or delete and reinstall the app to reset local data.
• Check that your phone OS is current, since very old versions can fail on new builds.
• Switch between Wi-Fi and mobile data to rule out a bad connection.

Grok Not Working in a Tesla

Grok in a Tesla depends on the car software version, an active data connection, and regional availability. If any of the three is missing, Grok will not appear or respond.

The feature rolls out with specific software updates, so a car on older firmware may not show Grok at all. Availability also varies by country and account type.

Because the car needs connectivity for Grok, a weak signal or an inactive connectivity plan will stop it. Park somewhere with good coverage before you troubleshoot further.

• Check for a Tesla software update in Controls, Software, and install any pending version.
• Confirm the car has a working data connection, ideally Premium Connectivity or a strong Wi-Fi link.
• Verify Grok is available in your region and for your account.
• Reboot the touchscreen by holding both scroll wheels until the display restarts.
• Make sure you are signed into your Tesla account with the right profile.
• Wait and retry if xAI is having a wider outage, since the car cannot fix a server problem.

Grok Not Working on PC or Web

When Grok will not load on a computer, the browser is the usual culprit. A stale cache, blocked cookies, or an aggressive extension can break the site.

Start with a hard refresh and a private window. A private window loads grok.com with no extensions and no cached files, which isolates the problem fast.

If the page loads but will not sign you in, cookies are likely blocked. Grok needs cookies enabled to keep your session.

• Hard refresh the page with Ctrl+Shift+R (Windows) or Cmd+Shift+R (Mac).
• Open grok.com in a private or incognito window to bypass the cache.
• Allow cookies for grok.com and x.com in your browser settings.
• Disable ad blockers and privacy extensions for the site, then reload.
• Try a different browser, such as Chrome, to rule out a browser-specific bug.
• Turn off any VPN, and confirm no firewall is blocking the domain.
• Clear your browser cache if the private window works but the normal one does not.

Grok API or Your Grok Bot Not Working

When the Grok API fails, the error usually comes from your key, your billing, or a rate limit. Read the exact status code, because it tells you which one.

A 401 means the API key is wrong, expired, or missing. A 429 means you are sending requests faster than your plan allows, or your credit has run out.

For a Discord or Telegram bot built on Grok, the same three causes apply, plus your bot token and hosting. Check the platform-specific setup if the API itself responds fine.

• Confirm your xAI API key is active and pasted correctly, with no extra spaces.
• Check your billing and credit balance, since an empty balance blocks requests.
• Read the status code: 401 is auth, 429 is rate limit, 5xx is a server error.
• Slow down or add retries with backoff if you see 429 errors.
• Verify your Discord or Telegram bot token and hosting are running.
• Check the xAI status page before assuming your code is the problem.

How to Check If Grok Is Down

To learn whether Grok is down for everyone, check the official xAI status page at status.x.ai first. It reports live outages and maintenance for Grok on the web and other surfaces.

Next, search X for phrases like Grok down. Real outages produce a wave of user reports within minutes.

Third-party monitors also aggregate outage data if the official page is unclear. If every source says Grok is up, the problem is on your end, and the fixes above apply.

• Open status.x.ai to see the official operational status for Grok.
• Search Grok down on X for real-time user reports.
• Follow @xAI on X for outage and maintenance announcements.
• Test Grok on a second device or network to confirm it is not just you.
• If all sources show Grok is up, work through the device fixes above.
