ERROR - ListenerManager Couldn't initialize the httpstransport listener - WSO2

Question

I started fresh copy of the WSO2 API Manager 1.8 and get below error for no reason.

ERROR - ListenerManager Couldn't initialize the httpstransport listener

How can I fix this?

Answer 1

Check the system hostname by running following command

$ hostname

try to ping to the output for that hostname.

$ ping <output of the hostname command>

If that gives an error check the /etc/hosts file. At least it should have a host entry to 127.0.0.1

127.0.0.1 <hostname>
or 
<local ip> <hostname>

Answer 2

Type

root@S-06:hostname
S-06

Type get your IP

root@S-06:ifconfig

Add it to vim /etc/hosts as a record.

192.168.4.123   S-06
