Why can't I access web interface

Hello all,
I am probably a slow moe on this but I am perplexed. I got my setup running, tested and performing perfectly. Knowing I was not going to brew for a month or so, i turned the brewpi off at the Web interface. Well this may be a very simple thing, but I can not seem to be able to access the web interface on my computer anymore. Do I need to reinstall scripts or something. I thought I should have been able to just plug in the address (XXX.XXX.X.XX) and it would pop back on?

I am using raspberry pi 2 (yeah I know old school, I had it before the Spark)

Or maybe a refresher on how to find what the address is?

Any help would be greatly appreciated!

Thanks in advance


I am a slow moe, wrong address. We cooking now!
