Hi

I'm currently working on SCION IP gateway(sig) from
https://netsec-ethz.github.io/scion-tutorials/apps/remote_sig/

Currently running two SCION AS from different server with different IP
using "SCION installation from sources" option
I checked bwtester is working between two servers (20-ffaa:1:c42,
20-ffaa:1:c5d), followed every step in the tutorial and double checked
config file
But I couldn't get "Hello World" message when I run curl command

the following is the sig logs I got

Both of the servers are showing the similar log
Is there any misconfiguration possibly made?


Best regards,
