Seems my server can't connect to ws0 thru the pulseway client, no, it is not a DNS or Internet error, the server in question can successfully ping the server.
pulseway: Error while registering online:SOAP 1.1 fault SOAP-ENV:Server[no subcode]#012"No route to host"#012Detail: connect failed in tcp_connect()
pulseway: Error while registering computer:SOAP 1.1 fault SOAP-ENV:Server[no subcode]#012"No route to host"#012Detail: connect failed in tcp_connect()
These are the two errors I get in syslog.
