You can only sign in to ZARMS with a Google account. You can use a company Google Workspace account or a personal Gmail account. However, only people who were invited can join an existing team. Choose the section closest to what’s happening.

You see “Google sign-in failed.”

Sign-in stopped partway through. Try these steps in order.
1

Try again

Wait a moment, open the sign-in screen again, and try once more.
2

Allow cookies

In your browser settings, allow cookies for app.zarms.cloud. If your browser blocks cookies, sign-in can’t finish.
3

Try a different setup

Sign in from a private (incognito) window or another browser. This also tells you whether an extension is causing the problem.

The Google sign-in button doesn’t appear

The Google sign-in component didn’t load. This is often caused by extensions such as ad blockers, or by restrictions on your company network. Turn off extensions for a moment, or try another network. If you’re on a company network, ask your network admin to allow connections to accounts.google.com. If you see “Google sign-in isn’t ready.”, wait a while and open the page again.

The team creation screen appears

The Google account you signed in with doesn’t belong to any team. If you were invited but still see this screen, one of these is likely:
  • You signed in with a different Google account than the one you were invited with: This often happens to people who use separate Google accounts for work and personal use.
  • You signed in before the admin created the invitation: Sign out once, then sign in again to join.
  • The invitation was canceled, or your access was suspended
  • The team you belong to is suspended or its subscription was canceled
1

Check the address

Ask the admin which email address they used for the invitation.
2

Sign in again with the invited account

Open app.zarms.cloud in a private (incognito) window and sign in with the Google account for the invited address.
3

Ask the admin to check the invitation

If you still can’t join, ask the admin to check on the members screen that your invitation is still there and that your access isn’t suspended.
If you were invited, don’t create a new team on this screen. Doing so creates a separate team, and you still won’t be in the team you were invited to.
If you were signed in with a different account when you opened the invite link, press Join with another account on the confirmation screen to choose another account.

You see “Page not found”

Either the URL is wrong, or you don’t have permission to enter that team. ZARMS shows the same screen whether a team doesn’t exist or you just don’t belong to it. For details, see Can’t find a screen or button.

You can’t get past the terms of use screen

You need to agree the first time you sign in and whenever the terms change. Once you check the box for every document, you can press Next. If you see “The terms could not be loaded.”, wait a moment and open the page again. If you see “Your session expired. Reload the page.”, reload the page.
