Hello,
I would like to know more data before stating for certain, but. here is what I get from the error: 

Either there is something up with a proxy service, or a node that is suppose to have 'Engine' running, doesn't some how. 

1. What is your overall architecture? 

2. Which node is throwing the error? 

3. As best you can, can you break out your virtual proxy mapping? 

Thanks
