# Can't sign in or verify account

Find the message you see below.

## Invalid email or password

Check the email for typos and try again. If you forgot your password, click **Forgot password?** on the **Welcome back** screen.

If you signed up with Google, use **Continue with Google** instead.

## An account already exists for this email

You already have an account with that address. Try another password, or use **Forgot password?**.

## Couldn't reach 3D-Agent

3D-Agent can't reach its servers. Check your internet connection, VPN, proxy or firewall, then try again. Antivirus tools that scan HTTPS connections can also block sign-in.

## Sign-in cancelled

You closed the browser window before you finished. Pick a sign-in method and try again.

## Confirm your email

Chat is locked until you confirm your email. Follow the link in the confirmation email. If you can't find it, check your spam folder.

## Reconnecting your session

3D-Agent couldn't verify your sign-in for a moment. It retries on its own. Wait a few seconds.

## Couldn't verify your subscription

The message underneath says what to do:

| Message | Fix |
| --- | --- |
| This sign-in is no longer authorized | Click **Sign in again**. |
| We couldn't check this account's plan status | Check your connection, then click **Retry**. |

If your plan still doesn't show after you sign in again, [open a ticket](https://3d-agent.com/docs/get-help) with your account email.

## I paid, but the app still asks me to upgrade

Your payment can take a moment to reach the app.

1. Wait a minute, then click **Retry** if you see it.
2. Check that you're signed in with the email you paid with.
3. Sign out and sign in again.
4. [Update 3D-Agent](https://3d-agent.com/docs/updates).

If it still asks, [open a ticket](https://3d-agent.com/docs/get-help) with the email you paid with and your receipt.

## Secure storage errors

3D-Agent keeps your session in your system's secure storage.

| Message | Fix |
| --- | --- |
| **Stronghold unavailable** | Restart 3D-Agent and accept the keychain or keyring prompt. |
| **Windows reported no interactive logon session** | Sign in to Windows directly, not through a remote or service session, then restart 3D-Agent. |

If 3D-Agent can't read its saved sign-in, it clears it and asks you to sign in again. This can happen after you move to a new computer or reinstall macOS. If you set a custom [Blender path](https://3d-agent.com/docs/connect-blender#use-a-blender-in-another-folder), set it again.
