Blynk.begin problem

every time when i reset my board (NodeMCU)
when i try to connect using Blynk.begin
i get the log message
[26102] Connecting to [Network SSID]
and it halts there - even though i see in my network (actually a hot spot i made in my Android) that the device is indeed connected
the only way to make the app continue is to turn off the hotspot and turn it on again
Only after this i can see the log continues to

[320138] Connected to WiFi

[320145] Connecting to blynk-cloud.com:8442
[320764] Ready (ping: 397ms).

how can i solve this issue?

When you create the hotspot are you expecting the MCU to connect to the Blynk server via 3G/4G/5G network or your phones WiFi?

Try removing the hotspot, reboot your Android, create a new hotspot with simple ssid and pwd.
Flash new details to MCU.

Thanks Costas for your reply
I have no way to configure “Tathering and Mobile Hotspot” on my galaxy 5
and i assume that it is not a 3/4/5G connection
just a simple ssid password like every other wifi router
on blyink.begin i ssuply the ssid and password
Blynk.begin(auth, ssid, pass);
and the connection is successful if after board reset i turn the hotspot off and on again
the same behavior is shown when using a standard wifi router too

You must have.
Enter your Hotspot via settings look for the menu button in top right corner
