Environment:
VPS, Java, MySQL, Wildfly 32 and other. The wildfly is configured as domain mode, I’ve configured /etc/hosts with my ipaddress and my domain name, I don’t have any kind of error in the wildfly log and nginx log. Below a piece of my domain.xml:

<subsystem xmlns="urn:jboss:domain:undertow:14.0" default-virtual-host="default-host" default-servlet-container="default" default-server="default-server" statistics-enabled="${wildfly.undertow.statistics-enabled:${wildfly.statistics-enabled:false}}" default-security-domain="itcmedbr.war">
                <byte-buffer-pool name="default"/>
                <buffer-cache name="default"/>
                <server name="default-server">
                    <http-listener name="default" socket-binding="http" redirect-socket="https" enable-http2="true"/>
                    <https-listener name="https" socket-binding="https" ssl-context="applicationSSC" enable-http2="true"/>
                    <host name="default-host" alias="itcmedbr.com,www.itcmedbr.com">
                        <location name="/" handler="itcmedbr-content"/>
                        <http-invoker http-authentication-factory="application-http-authentication"/>
                    </host>
                </server>
                <servlet-container name="default">
                    <jsp-config/>
                    <websockets/>
                </servlet-container>
                <handlers>
                    <file name="itcmedbr-content" path="/opt/wildfly/domain/servers/itcmedbr-server/data/content/03/ff88b34385221afb3b60df2252dd62e9ae9d68/content"/>
                </handlers>
                <application-security-domains>
                    <application-security-domain name="other" security-domain="ApplicationDomain"/>
                </application-security-domains>
            </subsystem>

I don’t have any idea how to solve this problem and I needing support to resolve this.
Thanks in advance.
