Hi,
I have a really weird bug and have no idea how to debug it.
I switch from netctl to iwd and since then (probably), some application cannot connect to the internet.
Specifically, I found two (both vital to my workflow):
1. terraform (a tool used to manage infrastructure written in go). It simply hangs when it tries to connect to the internet (it worked before). I tried to strace it and it just "refuses to connect"/connection timed out https://gist.github.com/hnykda/132e4948 … 806f528d8f . Weird thing is that it can connect when I try it from within a docker container.
2. rescuetime (https://www.rescuetime.com/): it simply cannot connect to the internet. It's more opaque so I can't easily debug it. (strace also just shows some connection timed out, but I am weak with strace)
s
Is there some "routing" or something I am missing? Can it be IPv6 vs IPv4 problems? DNS? Aside from netctl, I also removed openresolv, wpa_supplicant and dialog packages.
Thanks a lot!

...that could lead to DNS issues, but have no idea how to solve it.
