@wanek … Thanks for your help.
But I had already setup everything regarding the blynk local server and everything is working fine too. Except I couldn’t access the admin_page (UI).
Can you clarify “couldn’t access”… 404 error? Connection not private error? BSOD error? Smoke pouring out of the back of the PC error… etc.
If it is the “Your connection is not private error”, then that is normal, just click through until it allows you… In chrome you have to click on Advanced then “Proceed to …”
PS Local Server is an Advanced stage of Blynk… not an “Absolute beginner” stage
If it is the “Your connection is not private error”, then that is normal, just click through until it allows you… In chrome you have to click on Advanced then “Proceed to …”
I’m facing this error… I tried this thing what you had told several times. Still not working.
Could you please tell me, how i have to access the admin panel??
@Gunner this is my existing server.properties … please check it Sir.
Correct me if I need do any change!

SIR, PLEASE CHECK THIS ONE & HELP WITH SUGGESTIONS
Then either your server (the java program) is not running or that is not the correct IP for the server hardware… we don’t know this stuff, as it is your network.
