So I went to the server (which is a desktop computer that stays at the company)
The power wasn't on. -0-;;;
When I turned it on, it worked fine.
I set it up yesterday, updated it, and then moved it to a different location. I turned off the power and left it like that ㅋㅋㅋ
No matter how much I think about it, it doesn't seem like I'll be coming to the company on the weekend. ㅠㅠ
