Git – Corporate Github behind proxy: Received HTTP code 503 from proxy after CONNECT

corporategitgit-configgithubPROXY

I am trying to clone from a corporate git repo, but always receive this error message after a while:

fatal: unable to access URL: Received HTTP code 503 from proxy after CONNECT

I have the following .gitconfig file:

[https]
    sslVerify = false
    proxy = https://proxy.corpadderess:8080
[http]
    sslVerify = false
    proxy = http://proxy.corpadderess:8080

If it is a corporate repo, you might want to ignore proxy settings. One possible solution to your problem is here:

Ignore proxy: export no_proxy=YOUR_CORP_DOMAIN_ON_GITHUB, where the domain name might be in the form of github.acme.net
Ignore SSL verification: git config --global http.sslVerify "false"

You could then clone the repo w/ git clone YOUR_HTTPS_CLONE_URL

Git – SSL certificate rejected trying to access GitHub over HTTPS behind firewall

The problem is that you do not have any of Certification Authority certificates installed on your system. And these certs cannot be installed with cygwin's setup.exe.

Update: Install Net/ca-certificates package in cygwin (thanks dirkjot)

There are two solutions:

Actually install root certificates. Curl guys extracted for you certificates from Mozilla.

cacert.pem file is what you are looking for. This file contains > 250 CA certs (don't know how to trust this number of ppl). You need to download this file, split it to individual certificates put them to /usr/ssl/certs (your CApath) and index them.

Here is how to do it. With cygwin setup.exe install curl and openssl packages execute:
```
$ cd /usr/ssl/certs
$ curl http://curl.haxx.se/ca/cacert.pem |
  awk '{print > "cert" (1+n) ".pem"} /-----END CERTIFICATE-----/ {n++}'
$ c_rehash
```
Important: In order to use c_rehash you have to install openssl-perl too.
Ignore SSL certificate verification.

WARNING: Disabling SSL certificate verification has security implications. Without verification of the authenticity of SSL/HTTPS connections, a malicious attacker can impersonate a trusted endpoint (such as GitHub or some other remote Git host), and you'll be vulnerable to a Man-in-the-Middle Attack. Be sure you fully understand the security issues and your threat model before using this as a solution.

$ env GIT_SSL_NO_VERIFY=true git clone https://github...
```

Git error: “Host Key Verification Failed” when connecting to remote repository

As I answered previously in Cloning git repo causes error - Host key verification failed. fatal: The remote end hung up unexpectedly, add GitHub to the list of known hosts:

ssh-keyscan -t rsa github.com >> ~/.ssh/known_hosts
