This line looks suspicious for me: Exception reading response; nested exception is: java.net.SocketTimeoutException: Read timed out It looks like a connectivity issue with your SMTP server.

I was having this problem with version 1.9.1.Final and I recently updated to version 1.9.8.Final and still have the problem. In my case I don't need to kill the keycloak server. The e-mail is sent a few seconds after the error page. I've seen the problem with email verification and reset credential email, I think it's with all types of emails. For how long does it waits for a response before throwing the read timed out exception? -- Att, *Leonardo Nunes* Analista de Sistemas leo.nunes(a)gjccorp.com.br Skype: leonardo.puc +55 (62) 3250-1462 *Grupo Jaime Câmara* www.gjccorp.com.br From: Stian Thorgersen <sthorger(a)redhat.com&gt; Reply-To: &quot;stian(a)redhat.com&quot; <stian(a)redhat.com&gt; Date: terça-feira, 28 de junho de 2016 08:03 To: Bruno Oliveira <bruno(a)abstractj.org&gt; Cc: Leonardo Nunes <leo.nunes(a)gjccorp.com.br&gt;, " keycloak-user(a)lists.jboss.org&quot; <keycloak-user(a)lists.jboss.org&gt; Subject: Re: [keycloak-user] Email timeout error What version?
