# GitHub Help
> Troubleshoot GitHub access in Pawtograder: missing repositories, organization invitations, username changes, and the wrong linked account
# GitHub Help
Pawtograder creates a GitHub repository for each of your assignments inside your course's GitHub organization. When that goes wrong, almost every symptom traces back to one of four causes: you have not joined the course organization yet, you are signed in to GitHub as a different account than the one Pawtograder has on file, your GitHub username changed, or the assignment has not been released yet. This page walks through each one.
A fifth symptom looks the same but is not an access problem at all: a rejected `git push --force`. Most assignments block force-pushes to your default branch, so a force-push after a rebase or an amended commit fails even when your access is perfectly fine. See [If You Pushed and Nothing Happened](/students/assignments/create-submission#if-you-pushed-and-nothing-happened).
Your starting point is the **GitHub Access Troubleshooting** page, which shows you exactly which GitHub account Pawtograder thinks you are and which repositories that account should be able to open.
## Opening the GitHub Access Troubleshooting page
Open the **Support & Documentation** menu in the top-right corner of any course page and choose **GitHub Help**. You can also press `g` then `h`, or search for "GitHub help" in the global search palette.
The page tells you three things:
* The GitHub username and numeric GitHub user ID your Pawtograder account is linked to
* Every repository that account should be able to open on GitHub.com, each one a direct link. The list covers your individual repositories and the repositories of any assignment groups you belong to.
* A **Sync GitHub Account** button, described below
## If your repositories are missing
Work through these in order, because each step rules out a different cause.
If the **Join course GitHub organization to access assignments** banner is showing on your dashboard, that is the problem: until you accept the invitation, Pawtograder cannot create repositories for you at all. See [If the organization invitation never arrived](#if-the-organization-invitation-never-arrived).
Pawtograder only creates repositories for assignments that have been released. An assignment your instructor has set up but not yet released has no repository yet, and nothing you do on this page will produce one.
Open GitHub.com in the same browser and check which account you are signed in as. If it is not the username shown on the GitHub Access Troubleshooting page, sign out of the other account and sign in as the linked one.
Click one of the repository links on the page.
If the repository opens in your browser but you cannot clone, fetch, or push it from your computer, the problem is between your computer and GitHub, not between Pawtograder and GitHub. Bring that result to your course staff: it saves them from re-checking the Pawtograder side.
If you can clone and fetch and only your *push* is rejected, your access is fine and this is not the page you need. See [If You Pushed and Nothing Happened](/students/assignments/create-submission#if-you-pushed-and-nothing-happened).
If you are certain you are signed in as the linked account and the repositories still are not there, click **Sync GitHub Account**.
## Sync GitHub Account
**Sync GitHub Account** re-reads your account from GitHub and repairs what it finds:
* It updates your stored GitHub username from GitHub itself, so a username change is picked up
* It re-invites you to your course organization's student team, and marks your organization membership confirmed if you are already in it
* It creates any missing repositories for released assignments and re-applies the correct permissions to your existing ones
When the sync makes a change, it says so and asks you to refresh the page. Refresh before deciding whether it worked.
You can sync at most once a day. Once you have synced, the **Sync GitHub Account** button stays disabled until 24 hours have passed. That is a rate limit, not a failure, and syncing again sooner would not do anything different. If the first sync did not fix your access, contact your course staff rather than waiting for the button to come back.
Pawtograder also runs this sync for you automatically when you log in, as long as you still have a course where your organization membership is unconfirmed. So if you accepted an invitation and the banner is still showing, logging out and back in is worth trying before you spend your manual sync.
## If the organization invitation never arrived
Until you join your course's GitHub organization, Pawtograder cannot create repositories for your assignments, and it shows a **Join course GitHub organization to access assignments** banner. The banner appears on your course dashboard, on your assignments list, and on each assignment page, so you can act on it wherever you notice it. It disappears once your membership is confirmed.
The banner offers:
* **Open GitHub Organization Invitation**: opens your course organization's invitation page on GitHub.com, where you accept it. GitHub sends the invitation to the email address on the GitHub account you linked, which is not necessarily your university address.
* **Help**: a popover repeating which GitHub account you linked and the date and time the invitation was sent
* **Resend invitation**: sends a fresh invitation, subject to the limit below
If accepting the invitation on GitHub gives you an error saying it has expired, use **Resend invitation** and accept the new one.
**Resend invitation** is available only when the last invitation is more than five days old, and it disappears from the banner entirely until then. If you declined the invitation sooner than that, you cannot resend it yourself: ask your instructor to resend it for you.
After you accept the invitation, refresh the page and the banner should be gone.
## If your GitHub username changed
Renaming your account on GitHub does not break the link to Pawtograder, but Pawtograder keeps showing the old username until it re-reads your account. Open the GitHub Access Troubleshooting page and click **Sync GitHub Account**. The sync looks you up by your numeric GitHub user ID, which a rename does not change, and updates the stored username. Refresh the page afterwards.
## If the wrong GitHub account is linked
Switching Pawtograder to a *different* GitHub account is not currently supported, and there is no self-service way to unlink the one you connected. Contact your instructor.
This is worth getting right the first time. [Welcome to Pawtograder](/students/intro) explains which account to pick when you first connect.
