When you click an Aircall invitation or password reset link and see an HTTP 400, "This page isn't working," or a blank page, the link itself is usually still valid. The cause is typically a safety redirect or click tracker added by your email provider that corrupts the URL before it reaches Aircall. This article explains why it happens and how to fix it.

Note: If the URL starts with a domain like safelinks.protection.outlook.com, urldefense.proofpoint.com, or protect.mimecast.com, your company's IT security tools are modifying the link. See Error when accepting an invitation email instead.

If you are not receiving Aircall emails at all, see Troubleshooting Aircall emails.

Symptoms

You click the Confirm email, Accept Invitation, or Reset Password button in an Aircall email and see one of the following:

  • A browser error: "This page isn't working," "HTTP 400," or "Bad Request"
  • A blank or near-blank page
  • A "checking link safety" redirect that never completes

If the error occurs consistently across different browsers, in Incognito/Private mode, and on mobile data with Wi-Fi off, the problem is with the link as it arrives in your inbox, not with your device or browser.

Why this happens

Some email providers route every incoming link through a safety-check intermediary before opening it in your browser. When that intermediary re-encodes or restructures Aircall's URL, the receiving server can no longer parse the request and returns a 400 error.

This is most common with personal webmail accounts (GMX, web.de, mail.com, Yahoo, AOL, Outlook.com, iCloud) and can also be triggered by browser extensions, antivirus software with link-scanning enabled, or VPN and proxy services.

Aircall sends invitations and password reset emails from noreply@notify.aircall.io. If you hover over (or long-press on mobile) the button before clicking, the underlying URL should begin with:

  • Invitation: https://brcs2zd1.r.us-west-2.awstrack.me/L0/https:%2F%2Femail-verification.aircall.io%2F...
  • Password reset: https://brcs2zd1.r.us-west-2.awstrack.me/L0/https:%2F%2Fauth.aircall.io%2Fpassword%2Freset%3F...

If a different domain appears before https://brcs2zd1.r.us-west-2.awstrack.me/, another tool is wrapping the link.

Note: Password reset links expire 1 hour after the email is sent. Invitation links remain valid for 15 days. If your link has expired or has already been used, request a new one before trying the steps below.

How to fix it

Try the options below in order. Most users are unblocked by the first one.

Option 1: Forward the email to a different inbox

The simplest and most reliable fix.

Steps:

  1. Forward the Aircall email to an address on a different provider (for example, a Gmail or work email address).
  2. Open the forwarded email from that inbox.
  3. Click the Confirm email or Reset Password button.

Once the link opens successfully, your account is active. You can continue logging in with your original email address.

Option 2: Copy the link and paste it directly into your browser

This bypasses the click-through redirect on most providers.

Steps:

  1. Open the email without clicking the button.
  2. Right-click the Confirm email or Reset Password button (or long-press on mobile) and select Copy link address.
  3. Open a new browser tab, paste the URL into the address bar, and press Enter.
 
Important: The pasted URL must begin with https://brcs2zd1.r.us-west-2.awstrack.me/L0/https:%2F%2F.... If anything else appears before that, your provider is rewriting the link even on copy. Use Option 1 instead.

Option 3: Disable browser extensions or antivirus link-scanning

Some security tools (including Avira Browser Safety, Norton Safe Web, Bitdefender TrafficLight, and McAfee WebAdvisor) and certain ad-blocker or privacy extensions intercept links for reputation checks, which can break long encoded URLs.

Steps:

  1. Open the link in Incognito/Private mode with extensions disabled.
  2. If that does not work, temporarily pause your antivirus software's web or link protection, then click the link again.
  3. If you are using a VPN or proxy, disable it and try once more.
