I tried to redo the tutorial man times following every step and code, as well as the blynk settings.
When i login to blynk using my laptop, it says that its online but in my phone, it says status offline. Right bellow the online status says disconnected from server.
Another thing im worried about is that the LED of the ESP8266 is not conistently on, it blinks a few times when i connect it to a micro usb then it disappears. Also the vibration sensor, only 1 led is working but if i remove 1 pin, both LEDs turn on.
i connected vcc to 3v, Do to Do and GND to G of the ESP8266.
When i upload the code to the ESP, it says done uploading but it also says
A fatal esptool.py error occurred: could not open port 'COM5': OSError(22, 'The semaphore timeout period has expired.', None, 121)
Please help,
Mod edit
Blynk credentials removed.

}
}
Disconnect all the sensor wiring from Esp.
Does IDE find your Esp when you connect it through USB?
Do you use usb-cable that is working properly (for data).
I wonder why you use analogRead for digital output sensor.
DO of the sensor means digital out.
D0 on Esp is wrong pin, and if connected to low, prevents Esp to boot.
If you want to use analogRead, you need to connect to A0.
I turned on the verbose output options like you've said. I tried uploading it and it says uploading successful and it doesn't have the "copy error message option" but it still seems like it doesn't work. I made sure to turn on notifications and follow the tutorial. Also, in the last line of message after it finished uploading, some of the texts turned orange while most at the top is white

but why do you then post this error-message that clearly indicates
that there was NO upload?!
If your upload would have been successfull then you would see someting like this

Hash of data verified.
additionally what you have posted as compile-log
Is maybe 1% of what the real verbose compile-log would print
I suspect what you call "upload" was the compile-process.
Anyway @ptillisch I do not use Arduino IDE 2.X (I still use version 1.8.19)
the serial monitor of IDE 2.X has a problem to copy all text (and probably will have until version 3.X coming in 2030)
Does the compile-log window have the same problem, that in case the compiling was successfull that then if there is a problem with uploading the "copy error-message-button is not there?
then draw a handdraw schematic like shown in the tutorial and post a picture of it.
by the way trying to supply a Sim-Module from the arduino is a really bad idea.
The Arduinos onboard-voltage regulator can not provide enough power for such a module.
You really need an external power-supply for the sim-module.
