PlatformIO thinks I don't have internet.

Steps to Reproduce

1. Create a NodeMCU ESP8266 Arduino Project
2. Upload the empty file

Actual Results

 *  Executing task: platformio run --target upload --environment nodemcuv2_ota 

Processing nodemcuv2_ota (platform: espressif8266 @^2.6.3; board: nodemcuv2; framework: arduino)
---------------------------------------------------------------------------------------------------
Library Manager: Installing lebuni/ZACwire for TSic @ 2.0.0
Error: You are not connected to the Internet.
PlatformIO needs the Internet connection to download dependent packages or to work with PlatformIO Account.

 *  The terminal process "platformio 'run', '--target', 'upload', '--environment', 'nodemcuv2_ota'" terminated with exit code: 1.

Expected Results

It gets the toolchain and successfully builds and uploads it.

Could you debug https://github.com/platformio/platformio-core/blob/develop/platformio/http.py#L183 ?

platformio-core/platformio/__init__.py

Line 56 in 6db3eb8

88.198.170.159 is not pingable.
When I ping registry.platformio.org, I don't get any response. But when I access it via a web browser, I get to the regular website.
But the GitHub IP and Domain are.

[niklasarnitz]

Using socket.create_connection never yields a positive result for me.

[niklasarnitz]

import socket

socket.setdefaulttimeout(2)

hosts = [
	"github.com",
	"185.199.110.153",  # Github.com
	"88.198.170.159",  # platformio.org
	"registry.platformio.org",
	"registry.nm1.platformio.org",
]

for host in hosts:
	print(host)
	s = socket.create_connection((host, 80))
	s.close()

Output:

github.com
Traceback (most recent call last):

Okay, via celullar it works.

It seems that my ISP is blocking the platformio.org IP...

[ivankravets]

Could you contact your ISP? What is the reason that they blocked PlatformIO?

[niklasarnitz]

As I said, It seems they blocked it.
Bc on my end there is nothing blocked.
I’ll contact them.
