Unable to connect to web interface

I’ve been on a multi-hour struggle to try and troubleshoot why I cannot connect to my .local address or even my pi’s IP address, either of which should bring up mainsail. I can connect to the pi via SSH and have done a fresh install of raspberry pi operating system and klipper/moonraker/mainsail via KIAUH twice. I’ve done the exact same install on an identical RPI that is working flawlessly.
the .local address and the pi’s direct IP address do nothing, but if I add :7125 at the end it pulls up:
"Welcome to Moonraker

You may have intended to navigate to one of Moonraker’s front ends, if so check that you entered the correct port in the address bar."

At this point I need a break and am completely exhausted trying to figure it out.
I have another raspberry pi running a print right now. I’ll shutdown that pi and try to connect again, maybe it has something to do with the fact there’s another pi running. they do not have the same .local address or IP address, they’re both perfectly unique. Maybe something to do with the ports. I just don’t know and am exhausted.

goodnight i’ll edit in the morning.
