What the Authentication Errors Means
The Authentication Errors appears when EXM detects an authentication problem that requires the application to restart. This can happen if your login token is invalid, your session has expired, your account status changed, or the app hit an authentication-related failure that it cannot recover from without restarting.
In short, EXM is forcing a restart so authentication can be rechecked cleanly.
Why This Happens
The Authentication error is typically triggered by one of the following:
your login session expired
your auth token is invalid or no longer accepted
the app could not verify your account correctly
your account was signed out elsewhere
EXM detected a user or account auth issue
a temporary connection or backend auth failure occurred
When this happens, EXM may close, restart, or ask you to relaunch so it can attempt authentication again. The codebase description for AuthRestartModal notes it is tied to an invalid token, user-banned state, or auth error that forces restart.
How to Fix the Authentication Error
Follow these steps:
Fully close EXM
Make sure the app is completely shut down before reopening it.Reopen EXM
Launch the app again and allow it to re-authenticate.Log in again if prompted
If your session expired, signing in again may immediately resolve it.Check your internet connection
Make sure EXM can reach its authentication services without interruption.Disable VPN or proxy temporarily if applicable
In some cases, network routing or filtering can interfere with auth checks.Make sure your system time is correct
Incorrect system time can sometimes create authentication issues.Restart your PC if the issue keeps appearing
This helps clear stuck processes or session conflicts.
If the Error Continues
If you still get Authentication Errors after relaunching:
sign out and sign back in if possible
make sure you are using the correct account
check whether your subscription or account status changed
contact support if the app continues forcing restarts
When contacting support, include:
the exact error name: (ex: VPN detected)
when it appears
whether it happens every launch or only sometimes
whether you recently changed accounts, passwords, or billing
whether you are using a VPN, proxy, or custom DNS
Important Note
This error does not always mean your account is permanently blocked. In many cases, it is just a session or token problem that needs a clean restart and re-authentication. Based on the error mapping you shared, this modal is specifically used for invalid token, banned user, or general auth failures that require restart.
