What were you trying to do?

I had a connection error with Github on Claude Code. I removed Github Claude Code application to add again, so maybe it can solve the problem.

What happened instead?

But when i try to install github claude app, it gives 404 error page.

When i try to install on "https://github.com/apps/claude" link, the install button on this page redirects to "https://github.com/apps/claude/installations/new/permissions?target_id=324311125" address, and it gives a 404 page again.

How can i solve the problem and install github claude app?
