body: <p>I have integrated re-captcha for user register in Keycloack and when it is loading the recaptcha div is not showing. 
  After some time it gives following timeout errors in Chrome console.</p>

  <p>I found this error reported here in [<a href="https://issues.jboss.org/browse/KEYCLOAK-4584]" rel="nofollow noreferrer">https://issues.jboss.org/browse/KEYCLOAK-4584]</a> but I am not so clear how the problem is addressed. </p>
  
  <p>Is there any possible way to fix this?</p>
