BasicHTTPClient not working ?

Basic Infos

Hardware

Hardware: NodeMCU v1.0 (ESP12E)
Core Version: 2.2.0

Description

Hi ! I'm new to the esp8266 world and I'm trying to test wifi using Arduino IDE and the NodeMCU dev board.
I have tested the Hello Server example and it works fine but now when I'm trying the BasicHTTPClient, the board crash when connecting to my AP.
I also tried to set an AP with my phone but the results remain the same...

Maybe it's a dumb problem but I'm stuck with it now :-(

Settings in IDE

Module: NodeMCU 1.0
Flash Size: 4MB/3MB
CPU Frequency: 80Mhz
Flash Mode: ?qio?
Flash Frequency: ?40Mhz?
Upload Using: ?OTA / SERIAL?
Reset Method: ?ck / nodemcu?

I also have problems regarding the HTTPClient...

[bistory]

I tested the same request in the same conditions using nodemcu lua 0.9.5 and it is working perfectly... I guess it is not a hardware problem :)

[innesm]

I couldn't get a simple HTTP GET working on either a NodeMCU, or a Wemos D1R2. The error: "connection refused". After pulling the label "2.2.0" it works - previously I was on the latest code.

[kaeferfreund]

should be fixed with edaae2c

[bistory]

@kaeferfreund thanks, I will test that ASAP !

[igrr]

Looking at the stack trace, i think this was actually the same issue as #1997. Anyway, should be fixed now in git version.

This seems te be an issue still. Copy/paste of example code and I get the 'connection refused'. Quadrupple checked the URL, read probably 100 tickets about this problem but not a solution anywhere. I use platformio, maybe they use an old version?

[riker65]

Have the same issue
running lolin and arduino ide

[manishsasmal]

i am facing the same issue. I think it might a problem with server. I am using a shared hosting from vultr.com i am getting error 400 Bad request. Server could not understand your request. but when i am using a shared hosting from others it is working perfectly. May be i am missing something in server part. I am using apache, php. When i am hitting the url from browser it is working perfectly but not from esp. If you find any solution please post here. my code is as below
