Hi Brian, great article, thanks you so much!
Unfortunately I spent quite some time over it, but couldn’t get it working: I kickoff the flow, but after logging in via Okta, OAuth2-Proxy always returns me a 403 Error, “Login Failed: Unable to find a valid CSRF token. Please try again.”.
I can reliably reproduce it on a remote Linux machine as well as on my Mac.
Any idea what might be wrong?
