Greetings @rodolfocorral,

 

Since you have reinstalled the manufacturing apps, can you create a new app key and put the new app key into your OPC server configuration.

 

Thanks,

Himanshu

I already updated the OPC server with the new HOST and key that i got from the Controls Advisor console and that didn't solved the problem.

Hi @rodolfocorral,

 

Which version of Manufacturing apps and ThingWorx Composer installed on your machine.

 

Looking at the logs seems to be an issue with validation properties. Could you please take the backup of validation.properties file from the location C:\ThingworxStorage\esapi and remove the file from the location.

 

After removing, restart the tomcat.

 

If the issue still persists, share your newly generated validation.properties and catalina.log file from the tomcat logs

 

Thanks,

Himanshu
