SCION IP Gateway (SIG) is not working

[SonProCode]

Hi everyone, I'm trying to set up the SIG following this link: https://docs.scionlab.org/content/apps/remote_sig.html
But SIG didn't work. When i ran the command curl -sfS localhost:30456/status, there was nothing:

I have verified the connectivity between the two ASes, and it is operating normally over SCION

Here was the log when i started the scion-ip-gateway.service:

I would appreciate it if you could help identify the cause of the error. Thank you!
