Ttn cli behing firewall

1

Hi everyone

I’m using ttncli from my home desk and everything is ok, I can list my devices, etc.
But when I’m using ttncli at work, behind a firewall then ttncli won’t work.
NB : The port 1900 is open

./ttnctl-linux-amd64 devices list
INFO Using Application AppEUI=XXXXXXXX2540000 AppID=xxxxxx_xxx_xxxx
INFO Discovering Handler… Handler=ttn-handler-eu
INFO Connecting with Handler… Handler=eu.thethings.network:1904
FATAL Could not get devices. error=Could not get devices for application from Handler: unavailable: connection error: desc = "transport: Error while dialing dial tcp uilds/thethingsnetwork/ttn/utils/errors/errors.go:249

strangely “applications list” and “applications select” work.

Any idea ?

Not looked at detail but this jumps out to me - not sure if that is correct or not but whlist you call out 1900 open, what about 1904? and is 1904 even right (though all 1900…)
