The problem statement should have hinted you to look at something that should be the same but are actually different. Analyzing closely, we can see that the IPs in the Wireshark log and the ones in the HTTP response don't match! In particular, the last block of each IP address is different. If we find all of these different blocks and convert them to ASCII, we get a string that contains the flag.
