I know this is a common issue that can usually be resolved by searching things up, but everything I try doesn't seem to work...
I have
- Port forwarded [correctly?]
- Ticked 'Disable UPnP' in the settings
- Turned off my firewall altogether
- & I don't have an anti-malware program
Is it possible that my ISP has somehow disabled my hosting abilities for whatever reason? forget AT&T
(I'm using an AT&T u-Verse modem/router)
Also, I'm hosting through dedicated but I don't think it makes a difference since in-game hosting results in the same situation...
