Hi Priyanshi Saxena​, please check this article: https://support.ptc.com/appserver/cs/view/solution.jsp?n=CS189387and let us know if it answers your problem.

[psaxena]

I have already read this document but it only states the possible causes without any substantial solution to it and furthermore the log files of error doesnt give any meaningful error message.

[psaxena]

the only understandable error message which i found in tomcat log was :

The web application [/Thingworx] registered the JDBC driver [org.postgresql.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.

Can we comprehend anything from this?

Hi Priyanshi, could you please attach/copy paste your tomcat log here?

Could you please check your tomcat configuration and ensure it points to the correct java path? The library should be located in the <java folder>/\bin\server\jvm.dll

How much space do you have on your harddrive?

[psaxena]

Hi Polina,

Yes the path is correct and I have enough hard disk space available around 400gb so that is not the issue.

[mpatel-21]

Re-install your tomcat , and Import again Thingworx

[psaxena]

uninstalling tomcat and then reinstalling it might result in loss of my thingworx data. Could you please elaborate the step by step procedure to be followed so that i don't loose my previous data.

[psaxena]

My Thingworx composer is loading properly on my server in which thingworx is installed but when i access it from another system using the ip of the server it gives me the error failed to return license.

I have already added the inbound and outbound rules in the firewall for 8080 port to allow access from any ip.
