I get the same behavior:
$ /usr/bin/curl -v http://127.0.0.1:2/
* STATE: INIT => CONNECT handle 0x600057ad0; line 1404 (connection #-5000)
* Added connection 0. The cache now contains 1 members
* Trying 127.0.0.1...
* TCP_NODELAY set
* STATE: CONNECT => WAITCONNECT handle 0x600057ad0; line 1456 (connection #0)
* Connection timed out after 300324 milliseconds
* multi_done
* stopped the pause stream!
* Closing connection 0
* The cache now contains 0 members
curl: (28) Connection timed out after 300324 milliseconds
$ /usr/bin/curl --version
curl 7.59.0 (x86_64-unknown-cygwin) libcurl/7.59.0 OpenSSL/1.0.2p
zlib/1.2.11 libidn2/2.0.4 libpsl/0.18.0 (+libidn2/2.0.2) libssh2/1.7.0
nghttp2/1.31.0
I also get an almost immediate 'failed to connect' notice on windows:
C:\>C:\UTIL\curl\curl.exe -v http://127.0.0.1:2/
* Trying 127.0.0.1...
* TCP_NODELAY set
* connect to 127.0.0.1 port 2 failed: Connection refused
* Failed to connect to 127.0.0.1 port 2: Connection refused
* Closing connection 0
curl: (7) Failed to connect to 127.0.0.1 port 2: Connection refused
with either version of curl:
C:\>where curl
C:\UTIL\curl\curl.exe
C:\Windows\System32\curl.exe
