[FTL] unexpected end of JSON input

[gprime31]

So upgrading from an earlier version works fine ( git pull ) but fresh install (git clone or go install) results in this error: [FTL] unexpected end of JSON input missing bracket or something?

[MetzinAround]

Did you do the recent install with PDTM or another method?

[MetzinAround]

Just realized you answered that.

could you try installing with PDTM and see if that still causes the error?

ok very strange, it works but some throw the error... same with asn numbers.

[gprime31]

tested on: OS: Ubuntu 20.04.6 LTS x86_64 and OS: Debian GNU/Linux 11 (bullseye) aarch64 have the error.

Linux Arch AMD-64 and Mint 21.1 AMD-64 work fine, no problems. is there something that comes with those distros by default that the others are missing?

I'm also getting this error for all options :/ I just checked pdtm and is up to date. Worked fine for me a few weeks ago. I'm using MacOS.

@gprime31 @HackTheBridge Thanks for reporting this bug - It seems like the final endpoint https://api.asnmap.sh/api/v1/asnmap?ip=xxx is returning for some reason an empty answer. I suspect it might be related to TLS configuration/certificates. I'll post an update as soon as we find the root cause. Thanks for your patience!
