Minecraft Server Timing Out

I host a Minecraft Java Edition server for me, my family, and my friends to play on. For most people, it works perfectly.

However, whenever I try to join it from my own network, the connection times out. I can't join my own server from my own network.

(the error code is "io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection timed out: no further information: [IP].lightspeed.rlghnc.sbcglobal.net/[IP]:[Port Number]")

(note: sometimes, the "Connection timed out" text is replaced with "Connection refused".)

(note: Being wired/wireless doesn't affect this error's persistence.)

This doesn't happen when I'm on a network outside of my own. Other AT&T-hosted places work perfectly, using my phone's data (verizon) as a hotspot works perfectly, and it worked perfectly on my previous ISP's network.

I have a hunch there's a setting I'm missing in my router settings that's stopping me from joining my own server, but I've disabled most firewall/security settings to no avail. 

Please help me. This problem's been living in my head for months and I'm absolutely stumped.

You can't hit the server on your local network when trying to connect from your local network using the public IP?  That's a situation where you need a router that supports NAT Loopback.

Unfortunately, none of AT&T's fiber gateways support that feature.  You'd have to get a third party router that supports that feature and then put that behind the AT&T gateway using IP Passthrough or DMZ+ mode (you don't say which gateway you have).

I just double checked, my router is a BGW320-500. Not sure how that'll affect things, given no AT&T Fiber Gateways allow for NAT loopback. 

This seems like something that should be a standard feature, letting users connect to themselves. It's frustrating, and has bred a distaste for AT&T in me.

Thanks a million for helping :]

I asked about the gateway model only because with the BGW models you use IP Passthrough and with the earlier Pace model, you need to use DMZ+ Mode.

I try not to defend AT&T's choice to provide such basic hardware, especially when even the basics they do have don't work all that well, but NAT Loopback isn't universally available on all aftermarket routers.  But it's a feature that I don't think would add to the build costs so I'm at a loss to explain why it's missing.
