Hi Team，

There‘s 'HTTP Status 500 – Internal Server Error' when I open Thingworx MFG Apps in browser. The error shows 'java.lang.NullPointerException' message.

I opened the MFG Apps with nothing wrong yesterday. I tried to restart the Configure PTC Servlet Engine, but it still shows the same.

I don't know how to deal with it, could you please help me? Thank you!

The error is like shown below:

Hi Mengjue,


The issue was related to the database service .

Restart of Postgres and ThingWorx server service resolved the issue.

Thanks,

Greetings Mengjue Liu,

The instance is not able to create connection with the database . The error thrown in the application logs is :

2017-11-09 09:44:10.354+0800 [L: ERROR] [O: c.t.s.ThingWorxServer] [I: ] [U: SuperUser] [S: ] [T: localhost-startStop-1] [message: Connections could not be acquired from the underlying database!].


Try restarting the services again after clearing the cache.

Regards,

Hi Mengjue,

Is this error thrown after you logged in to the Welcome page ?

Could you please attach the application logs after you did the restart ?

Thanks,
