[SOLVED] I can't connect to my local server

Blynk Servers Local Blynk Server
1

first of all i’m very sorry for my english i’m not good at it.
i install local server step by step and after : java -jar server-0.16.2.jar -dataFolder /path i get the message : Blynk Server successfully started. with IP: 192.168.1.54 for example and port 8443
i go to blynk app and in custom mode change the IP and port and in sketch changed
Blynk.begin(auth, “saberi”, “Password”, “192.168.1.52”,8443);
but when i upload the sketch i see following message in my serial monitor in see nothing in blynk app ( application says : your ESP8266 in not in network )
[44705] Connecting to saberi
[44705] Connected to WiFi
[44705] IP: 192.168.1.54
[44705] Blynk v0.3.7 on ESP8266
device alive, go to phone app
[107005] Connecting to 192.168.1.52:8443
temperature: 29.70 *C
humidity %68.80
[113399] Connecting to 192.168.1.52:8443

2

should be

Blynk.begin(auth, "saberi", "Password", "192.168.1.52");

i remove the port number and esp connect succesfully but after about 10 result i get following message in serial monitor:

[188571] Connecting to 192.168.1.52:8442
temperature: 28.40 *C
humidity %59.90
[194961] Ready (ping: 6376ms).
[199963] Login timeout

before when i used blynk cloud server i got this message so i changed my path to local server:
what should i do now ? is it because of baud rate ? my baud rate is 57600.

Too many delays. You need to get rid of them.
