Description:
I cannot connect to one specific Wifi network using netctl. The response is:

However, manual connection works without a problem, so the password is correct:
wpa_supplicant -B -i wlp3s0 -c <(wpa_passphrase myssid mypassword)
dhcpcd wlp3s0

Additional info:
* netctl version 1.28

config:
Description='A simple WPA encrypted wireless connection'
Interface=wlp3s0
Connection=wireless
Security=wpa

IP=dhcp

ESSID='myssid'
# Prepend hexadecimal keys with \"
# If your key starts with ", write it as '""<key>"'
# See also: the section on special quoting rules in netctl.profile(5)
Key='mypassword'
# Uncomment this if your ssid is hidden
#Hidden=yes


Steps to reproduce:
netctl start wifi
