Hello, I'm trying to connect remotely from WAN via my FQDN LAN 0 address and getting no response. I checked the unraid-api logs and found the following:

what unraid version are you running? also, does running unraid-api restart fix this specific error? and does your server show up in the Connect Dashboard (ie it's online and you can see the server's details)?
