Captive portal not redirecting but Radius and pfsense show auth successful 2.2.6

[kapara]

This has worked for the longest time on 1.2.  I re-used the same page on 2.2.6 so not sure if that is the proble.

Using the following:

<form method="post" action="$PORTAL_ACTION$">
Username:

Password:

</form>

Checkout your Services => Captive Portal => CP-ID => Configuration page.
Something is missing in your 'html'  ;)
