Question

HTTP Status 404 - /Thingworx/Home

I have this issue:
If I'm working on ThingWorx, and I'm start doing something else for a while (like half an hour) when I go back on ThingWorx and I refresh the page I have apache problem:

HTTP Status 404 - /Thingworx/Home

type Status report

message /Thingworx/Home

description The requested resource is not available.

Apache Tomcat/8.0.20

It doesn't happens ALL the times but like 50% of the times so I don't understand on what it depends.

So far I can only solve the problem by uninstalling and re-installing Apache Tomcat

Have you had a look at the Apache error log - is there any reference to this? Does the Apache service continue run while you get this error?

Yes, I've seen in the folder C:\PTC\Tomcat\logs end I don't have any error file.

I've also seen in C:\ThingWorxStorage\logs and the ErrorLog file is empty.

The only message I got I have in C:\PTC\Tomcat\logs\catalina.2016-05-02.log which gives me this message

Fabio, do you have a proxy server or any form of re-director or port forwarding involved? /Thingworx/Home will usually resolve to /Thingworx/Composer/index.html.

    Fabio,

    Just an fyi, make sure you are not using Tomcat 8.0.30 or above. I had this HTTP 404 problem with 8.0.30 and 8.0.33 (though it is intermittent).

    Deploying Thingworx instance in 8.0.24/26 fixed my issue. Not exactly sure about the root cause.

    Fabio, please do post your logs. And on a side note, what version of Java are you using?

    Just a clue:
    May it depends on the fact I'm working on my local computer and not on the Virtual Machine?

    Hi All,

    Even I am facing the same issue. the error I get is in attached screen shot. I feel it is not getting deployed successfully.

    The error occurs for version 6.5 and above. Version 6 is getting deployed successfully.

    My system configurations are:

    Java version 8

    and Apache tomcat version 8.0.36.

    I just solved my problem working on my Virtual Machine instead of local.

    I don't know how this affects the problem itself but it works.

    Hi Guru, it appear as though the Postgresql isn't reachable or correctly configured. Have you check the postgresql installation? Could you connect to it? does it contain ThingWorx schema along with its tables?

    Is this a fresh installation or was this setup working before?

    We experienced the same problem and we could solve it just changing the java version from 1.8_121 to 1.8_92, that it was the recommended version in the installation guide.

    I don't know if this can help you Fabio Manniti​.

    I don't have anymore this problem.
    I just solved it working on my virtual machine instead of local.
