Tomcat - This is a proxy server. Does not respond to non-proxy requests.

[Sathishkumar_C]

Hi,

We have installed Thingworx 8.5 with Tomcat 8.5. It was working properly. But, after sometime it is showing "This is a proxy server. Does not respond to non-proxy requests." message while trying to open tomcat. What will be the issue? How to resolve?

Thanks & Regards,

Sathishkumar C.

Hello,

Thank you for your post.  Hopefully we can resolve this issue together.  Did you happen to use a proxy configuration in your config.json file during installation?

Thank you,

Hello,

I'd actually like to take a step back and get a better idea of the system you're working with.  Can you please provide the following details?

• Java Version
• OS (windows, ubuntu, RHEL, Amazon RDS)
• Persistence (H2, PostgreSQL, DSE, Azure, etc)
• Where exactly are you seeing the error message?  (Is it in a Tomcat log?)
• Do you have any error logs to share?
• Have you successfully launched ThingWorx platform and created and saved an Entity?

Thank you,

Angela

Hi,

Please find details below,

• Java 1.8.0_171
• Windows 10 Home
• PostgreSQL 9.4 Thingworx
• PostgreSQL 9.6 for Streams (Persistance Provider)

Both the servers installed on same system.

Thanks.

Hi,

I have seen in catalina.log the following:

For me this seems that the 8080 port is already used.

Please follow the steps from this article: https://www.ptc.com/en/support/article?n=CS290811
