System may be unstable: HTTPS WSO2 EI 6.6.0

I have the next error in the product WSO2 EI 6.6.0.

I am only trying to do a call mediator

  <call>
    <endpoint name="GETToken">
      <address uri="api.backend"/>
    </endpoint>
  </call>

I am using a proxy in the axis2.xml file and in the integrator.sh file like:

axis2.xml

<transportSender name="http" class="org.apache.synapse.transport.passthru.PassThroughHttpSender">
    <parameter name="non-blocking" locked="false">true</parameter>
    <!--<parameter name="warnOnHTTP500" locked="false">*</parameter>
    <parameter name="http.proxyHost" locked="false">proxy.com</parameter>
    <parameter name="http.proxyPort" locked="false">8080</parameter>-->
    <parameter name="http.nonProxyHosts" locked="false">.*.domain.com|localhost|10.*.*.*</parameter>
</transportSender>

<transportSender name="https" class="org.apache.synapse.transport.passthru.PassThroughHttpSSLSender">
    <parameter name="non-blocking" locked="false">true</parameter>
    <!--<parameter name="http.proxyHost" locked="false">proxy.com</parameter>
    <parameter name="http.proxyPort" locked="false">8080</parameter> -->
    <parameter name="http.nonProxyHosts" locked="false">.*.domain.com|localhost|10.*.*.*</parameter>
    <parameter name="keystore" locked="false">

integrator.sh

 -Dhttps.proxyHost="proxy.com" \
    -Dhttps.proxyPort="8080" \
    -Dhttp.proxyHost="proxy.com" \
    -Dhttp.proxyPort="8080" \
    -Dhttp.nonProxyHosts="localhost|10.*.*.*|*.domain.com" \

I see the next question, but it hasn't any response:

Error in EI - System may be unstable: HTTPS ConnectingIOReactor encountered a runtime exception

Solution

  • The problem was related with HostName verification, so I change the next line

    <parameter name="HostnameVerifier">Strict|AllowAll|DefaultAndLocalhost</parameter>

    in the axis2.xml that you can find in the route: wso2ei-6.6.0\conf\axis2
