Area

apps/web

Steps to reproduce

  1. Use winget to install new instance.
  2. click Sign in to T3 Connect
  3. choose Sign Up
  4. Try to use github or google options.
  5. Goes to github auth page and returns to t3 code with an empty page and then bugs the entire account registration process.

Expected behavior

Choose Github to link new account, OAuth connects and returns to the Application with new account linked.

Actual behavior

Can't make a new account and gives error:

The current redirect url passed in the sign in or sign up request does not match an authorized redirect URI for this instance. Review authorized redirect urls for your instance. t3code://app/CLERK-ROUTER/VIRTUAL/sign-up#/settings/connections

                          Before submitting

                          • I searched existing issues and did not find a duplicate.
                          • I included enough detail to reproduce or investigate the problem.

                          apps/web

                          Steps to reproduce

                          1. Use winget to install new instance.
                          2. click Sign in to T3 Connect
                          3. choose Sign Up
                          4. Try to use github or google options.
                          5. Goes to github auth page and returns to t3 code with an empty page and then bugs the entire account registration process.

                          Expected behavior

                          Choose Github to link new account, OAuth connects and returns to the Application with new account linked.

                          Actual behavior

                          Can't make a new account and gives error:

                          The current redirect url passed in the sign in or sign up request does not match an authorized redirect URI for this instance. Review authorized redirect urls for your instance. t3code://app/CLERK-ROUTER/VIRTUAL/sign-up#/settings/connections
