401 from Cloudflare Access after Login - Occurs only when clicking link

What is the name of the domain?

qt.x.nl

What is the error number?

401

What is the error message?

Unauthorized

What is the issue you’re encountering

Direct access to https://qt.x.nl/ works fine after Access email login. However, clicking a link to https://qt.x.nl/ from https://x.nl/ (or refreshing the page after clicking the link) not.

What steps have you taken to resolve the issue?

  • Tunnel works (direct access proves this).
  • Suspected Access policy, but deleted and recreated the Access application for qt.x.nl. Issue persists.
  • Cleared browser cache/cookies, tested Incognito/other devices - same result.
  • Rocket Loader is OFF for x.nl.

Cloudflare Access is denying authorization after successful login, only when navigating via a link click or refresh. This persists even after deleting/recreating the Access application,

What are the steps to reproduce the issue?

  1. Go to https://x.nl/ in a web browser.
  2. Click the “qBittorrent” link.
  3. If prompted, log in using Cloudflare Access with the authorized email address.
  4. Observe the resulting page (expecting the qBittorrent web UI, but receiving a 401 Unauthorized error).
  5. Alternatively, after step 3, refresh the page at https://qt.x.nl/ and observe the 401 Unauthorized error.
  6. Compare this behavior to typing https://qt.x.nl/ directly into the address bar and hitting Enter (which works after login).

I can provide real URL’s but don’t like exposing them in the open.
