Troubleshoot NextCloud Server

[ShadowWolf810]

Hi all, I feel like I've been posting a ton in this thread recently. I'm working on building a media server for editors in a production environment. On the fence about whether to use FreeNAS or not, but I think I've settled on NextCloud for the web interface part. 

 

I wanted to play with it before I put it on the real machine, so I followed a guide to install it on my laptop which has Linux Mint 18. Everything went smoothly and it all worked, even with my super limited experience with Linux and Apache. Went to show my professor at school today and realized the IP was configured for my home network and I'd just need to change the server ip. So I found all the config files that I could and changed the IP to the one my laptop got from DHCP on campus. Still couldn't get it to work, figured their routers were the problem. Came back to my house and changed all the config files back to original IP, and now I can't get it working here either. 

 

I've been reading the documentation and looking up Youtube tutorials, I also posted on the NextCloud forums as well but no one will reply. If anyone out there is more familiar with NextCloud I'd really appreciate some tips on how to configure everything, or if you can point me to the right resources that'd be great too!
