Failed to connect to bitbucket.org port 443: Network is unreachable

Question

I am getting issue while pushing code.

git push origin master  fatal: unable to access 'https://[email protected]/xxxxxx/xxxxxx.git/':  Failed to connect to bitbucket.org port 443: Network is unreachable 

How to avoid that error message?

Answer 1

TLDR; Try first git push -4 origin master

There are issues reporting current problems to access bitbucket through https (issue 13060, issue 12184)

The usual answer is:

"Failed to connect" errors could be anything from DNS issues to local network problems to ISPs that are incompletely routing Bitbucket traffic. Unfortunately, there isn't enough detail in any of these comments to diagnose the exact problems, which may or may not be related to each other. If you could, please open a support ticket with the results of the following commands:

For OS X, Linux, and other UNIX-based operating systems:

ping -c10 bitbucket.org ping6 -c10 bitbucket.org traceroute bitbucket.org traceroute6 bitbucket.org GIT_CURL_VERBOSE=1 git ls-remote https://bitbucket.org/bitbucket/do_not_delete 

For Windows:

ping -n 10 bitbucket.org ping -n 10 -6 bitbucket.org tracert bitbucket.org tracert -6 bitbucket.org 

(To clarify: "ping6" and "traceroute6" are the IPv6 equivalents of "ping" and "traceroute", respectively, and "GIT_CURL_VERBOSE=1" before any git command will detail all the HTTP-specific parts of the connection.
On the Windows side of things, the "-6" in the command line specifies that your computer should use IPv6 for the ping or tracert.)

Additionally, if you suspect that your problem is related to Bitbucket's IPv6 support, then you should be able to test your overall IPv6 connectivity by opening the following links in your browser:

https://ipv6.google.com https://www.v6.facebook.com 

Those links should not work at all if your IPv6 connection is disabled or misconfigured.

More generally, check your /etc/hosts for any entry regarding bitbucket.org.
See "What are the Bitbucket Cloud IP addresses I should use to configure my corporate firewall?"

The IP address has recently changed:

Since July 28, 2018: IPv4 inbound for bitbucket.org, api.bitbucket.org, and altssh.bitbucket.org

18.205.93.0/25 18.234.32.128/25 13.52.5.0/25 

Keep in mind ping might be blocked, triggering the same error message.

The IPV6 can be problematic: the same thread advises:

This is probably coming when git is trying to push over IPV6. I'm not exactly sure why getting this error with IPV6. But here are different solutions, that you can use to fix this problem.

Add any one of the following IP into /etc/hosts file to force git to use IPV4

104.192.143.2 104.192.143.3 104.192.143.1 

That is,

104.192.143.2 bitbucket.org 

To /etc/hosts file

(Or)

Upgrade your git to latest version. Probably this could solve the problem else use the following option when you push after you upgrade git (this feature was added newly to git)

 -4, --ipv4 use IPv4 addresses only 

That is ,

git push -4 bitbucket dev 

You can specify this option -4 while you push, pull or clone.

(Or)

You may configure git to use http proxy to solve this problem

 git config --local http.proxy http://proxyuser:[email protected]:8080 

If you are already using latest version of git, you can simply use option -4 to force git to use IPV4 address or you can go with /etc/hosts

If you wanna see debug message while pushing or pulling code you can set following environment variable before you do so,

export GIT_CURL_VERBOSE=1
