Cannot create another blocks conf error

Hi everyone,

Im stuck on one of my blocks. I have 6 blocks running but i add another blocks jpm, create a jpm.conf for it in conf.d and other setting just like the running blocks. then restart the nginx service it will stopped. All my blocks were down. All i need to do is rename jpm.conf to jpm, then start the nginx service and it will start the service.

So my question is why i cant add another site?
