Blynk wont connect to local Server

[NicoF2000]

Hello,

my NodeMCU (ESP8266) can’t connect to the local Blynk server.
I used a Raspberry PI before, but now I moved the server to an real server.
The app connection seams to be fine. I am using the latest version of the Blynk app on Android.
I installed the Blynk library using the board manager url.

This is my Code (I removed private informations.)

#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
char auth[] = "";
char ssid[] = "";
char pass[] = "";

void setup() {
  Serial.begin(9600);
  Blynk.begin(auth, ssid, pass, IPAddress(192,168,178,6), 8443);
}

void loop() {
  Blynk.run();
}

And this is the Serial output:

[45] Connecting to SSID

[2627] Connecting to 192.168.178.6

Hope that we can solve the problem…

Try port 8080 in the code.

Blynk.begin(auth, ssid, pass, IPAddress(192,168,178,6), 8443);

Yes, yes we can…by reading the Announcement topics and searching the forum before posting questions… Local Server has required port 8080 for months now.

PS, and since when did 8443 ever get used in a sketch anyhow? That was the old port for in the App… now replaced by 9443 for Local server (I think just 443 will work on Cloud)

Upcoming Android 2.18.0 update (IMPORTANT for local server owners)

Dear all, in the next few days, we will release new Android update. This update has only 1, but very important change. Blynk app from now will use 443 (default https) port instead of 8443 in Blynk Cloud. This change is required as in many cases 8443 port is blocked by default in some networks. Update may affect existing local servers. Default app connection port for the local servers will be moved from 8443 port to 9443 port. The new app will connect to 9443 port of the local server by defaul…

New Blynk Library v0.5.1 is Released (important for local server owners)

In this release New hardware support: TI CC3220 (Energia IDE) General improvements Blynk switched to using port 80 by default. Certificates added for easier switching from Blynk Cloud to Let’s Encrypt Add setMin & setMax to widgets Bugfixes: Fix pinMode command Fix ESP32 WiFi credentials provisioning PlatformIO, Particle, ARM mbed and OpenWRT packages have been updated accordingly. Full list of supported hardware is available here NOTE: if you have local server and uploa…

The better way for to do that all people read a post is to title it as: “Don’t read this!!”

Too much publicity has made us insensitive to notices. I think the only one manual that almost all men will read is the washer manual… and only after no more underwear clean XD

[NicoF2000]

Thank you Working now. I haven’t used Blynk for a long time… I found this code in the examples so I thought that the port would be correct…

[Gunner]

Blynk is in constant development… so unfortunately documentation and examples take time and effort to catch up But that is also why it is important to keep up with the Announcement topics and Forum search.

Glad it is working again for you!
