s.d.engineering · June 8, 2017, 8:45am

G:\BlynkLocalServer>java -jar server-0.24.4.jar -dataFolder ./data

All server output is stored in folder ‘G:\BlynkLocalServer.\logs’ file.

Dmitriy · June 8, 2017, 8:48am

This error possible only in case you didn’t specify server.host or you are using wrong server.properties where you didn’t put server.host. Also please try yo use latest server I don’t remember exactly in which version this poroperty was changed.

s.d.engineering · June 8, 2017, 8:51am

on server properties i just modified the :

server.host=192.168.1.2
and
contact.email=******@gmail.com
and

Where is your server.properties? How exactly do you run the server?

s.d.engineering · June 8, 2017, 9:12am

on same folder .jar file

inside the .bat file is :
java -jar server-0.24.6.jar -dataFolder ./data

Gunner · June 8, 2017, 9:19am

Just to be sure… the IP 192.168.1.2 you are using is the same one used for your PC, running Win7 (on which you have installed Blynk Server), and NOT the IP for your router?

Dmitriy · June 8, 2017, 9:20am

Please try to add -serverConfig FULL_PATH_SERVER_PROPERTIES to your bat file. Seems like properties are picked from wrong location because of bat file.

For example c:/server.properties
