Can't connect to pigpio at localhost(8888)

Did you start the pigpio daemon? E.g. sudo pigpiod

Did you specify the correct Pi host/port in the environment
variables PIGPIO_ADDR/PIGPIO_PORT?
E.g. export PIGPIO_ADDR=soft, export PIGPIO_PORT=8888

Did you specify the correct Pi host/port in the
pigpio.pi() function? E.g. pigpio.pi('soft', 8888)

I tried changing the intr_pin in the config.inf file but with no luck

Most of the buses on your RPi (SPIx, I2Cx, etc.) need to be set up and or enabled.

Check to see if SPI is enabled with ls /dev/spi*

if you see something like:
crw-rw---- 1 root spi 153, 0 Aug 31 18:23 /dev/spidev0.0
crw-rw---- 1 root spi 153, 1 Aug 31 18:23 /dev/spidev0.1

then SPI0 is enabled. if not use raspi-config to enable it.
if you are connected to SPIx which is not SPI0 then you will also need to enable a driver for it by editing /boot/config.txt

Also, it looks like you may not have started the pigpiod service.

Please follow the instructions to enable and then start the pgpiod.serice.
👍
Also make sure your interrupt line is on the GPIO pin you expect and that gpio pin number is correctly entered into your config.ini

Does this help?

It turned out to be a hardware problem
I tried another raspberry pi and everything worked fine
