Problem authenticating to self-hosted instance

[tino]

Environment

self-hosed Sentry 25.6.0.dev0; cli: 0.13.0

Steps to Reproduce

`SENTRY_URL=https://sentry.mydomain.com sentry auth login

Expected Result

Log in?

Actual Result

I see a html response, with the main part being:

    <section class="body">
        <div class="page-header">
            <h2>CSRF Verification Failed</h2>
        </div>

        <p>A required security token was not found or was invalid.</p>

        <p>If you're continually seeing this issue, try the following:</p>

        <ol>
          <li>Clear cookies (at least for Sentry's domain).</li>
          <li>Reload the page you're trying to submit (don't re-submit data).</li>
          <li>Re-enter the information, and submit the form again.</li>
          <li>Ensure the URL does not contain an extra  &quot;/&quot; anywhere (eg: https://foo//saml -> https://foo/saml).</li>
        </ol>

---

Note that the SENTRY_URL isn't documented anywhere. I had to find it through issue and code diving.

Thanks a lot for the report @tino!

This version of Sentry (25.6.0) does not have the device authentication endpoint that we use for auth login flow so you'd need to upgrade it for a better experience. That said you can still use the CLI by generating a token yourself in the UI once and then running sentry auth login --token=<your_token>

I'll be updating the docs regarding SENTRY_URL, apologies for that.
