Work through these in order. The most common causes come first.
1. The only page you can open is your application (the waitlist page)
You are signed in but have not been let in yet, and you do not hold a role in any workspace. Until you do, you can only see your application. See "How do I get access to Nebula Rosterr? (waitlist and early access)". If an admin has already added you to a workspace, sign out and in again.
2. You are signed in, but no workspace appears
You need a role in the workspace. Ask a workspace admin to check that your Roblox rank is connected to a role (Settings > Permissions) and press Sync Group, or to add you by hand.
Check you are signed in as the right person. If you have two Discord or Roblox accounts, you may have signed in with the wrong one. Each Rosterr account links exactly one Roblox and one Discord account.
The workspace may be suspended. You would see a "workspace suspended" page. Only the workspace owner can sort this out with the Nebula team.
3. Sign-in fails or loops
"Sign in with Roblox isn't available right now." Use Discord instead.
"This Roblox account is already linked to a different Discord account" (or the reverse). Sign in with the pair you used the first time.
Your browser blocks cookies for Rosterr. Allow cookies for the site, and avoid private windows that clear them on every page.
You are on a custom workspace address (such as staff.yourgroup.com) and are not a member of that workspace. You will see "You're not a member of this workspace".
4. You are signed out unexpectedly
Sign-ins last about 30 days and renew each time you use Rosterr. If you did not use it for a long time you need to sign in again.
Someone may have used "sign out everywhere else", or your account may have been blocked or banned by Nebula staff. If you think this is a mistake, contact support.
5. You can sign in but a page or button is missing
That is almost always a permission. See "Find your way around a workspace (the menu explained)" and ask an admin to check your role. Features can also be switched off for the whole workspace under Settings > Features.
6. Phone app sign-in
See "Sign in on the phone app (browser sign-in and the code method)" and "Phone app troubleshooting".
Still stuck?
Contact support through the Help and Support chat or at [email protected]. Tell them your Roblox username, your workspace's group ID, what you see on screen (a screenshot helps), and what you have already tried.
