So I'm having a terrible, frustrating time with running a server. I've gone through the set up a million times before, on a previous laptop, and have had no issues before on launching and hosting servers what so ever besides the occassional port-forwarding, which was a quick fix. Now that I have a new pc, I decided to set up a new modded server to take a whack at playing with friends once more. I could connect or see that other hosted servers were online, but any address that I used to connect to mine just couldn't "reach the server." When I mean address, I tried localhost, 127.0.0.1, 0.0.0.0, my own IPv4 address used via my router, with nothing working at all. From my understanding, localhost always works, as long as the server is running on the same machine, which is the case that I had. Console and client were both running at the same time, and Localhost just acted like nothing was going on. I even went through the trouble of checking my ports, and according to canyouseeme.org 25565 is open, and I took a stab at my own external address, even with the :25565 at the end. I also did this with the several previous addresses, nothing.
This made me believe that it had to be a software issue, and not a network one as I was going through localhost. So I deleted everything. I made the server vanilla, the client vanilla. I even redownloaded the minecraft_server.jar, and the minecraft.exe. I even tried the minecraft_server.exe, no avail. For whatever reason, localhost refuses to work as a way to connect, and I feel like if that was solved, all of this would be.
EDIT: I'll also mention that I had 32 bit Java 7 installed on my 64 bit computer, that didn't work. So I've unistalled it, and went through the trouble of even reinstalling with the 64 bit to fix the issue. This did not work. I'll also repeat, if it wasn't apparent, I can easily connect to other servers. Modded clients, or vanilla ones.
