@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).
Kindly help me.
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 
also it would be nice to know how did you tried to access?
@Gunner …

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??
Please cross check my server.properties file.
First if your screen looks like this in the middle,
Then click on ADVANCED…
…then click on proceed, witch should take you to the Admin login
try this:

Please read the documentation in all the links above… you are using the wrong port, should be 9443 for the Admin page.
Sorry, I haven’t used MQTT so I am unfamiliar with any of it’s requirements… and thats a question for a different topic.
Have you successfully achieved the Admin page?
@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
I have already that Sir.
And yet you missed the correct port Read the entire topic.
Assuming that this IS the correct IP for your Server, the Admin page should be accessable like this.
https://192.168.42.43:9443/admin
@Gunner … Sir, I changed it as per your instruction to 9443.
still the problem remains as such.
See the screenshot below Sir.
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.
how do you know that your local server is actually running?
This is NOT the correct port!
The server is running properly because I can connect my blynk app and work with it using Arduino UNO.
Sir, please tell how to find ip for my server and my correct port
did you actually read any topic on this forum how to do this?
all was explained several times…
As per your request and my last post… You. Have. The. Wrong. Port. In. The. server.properties
