問題

• As a result of enabling IPv6 connectivity for Bitbucket Cloud, some users may have trouble accessing Bitbucket Cloud.

診断

• When performing GIT operations, you may encounter errors such as:

  "error: RPC failed; curl 52 Empty reply from server" 
  "Failed to connect to bitbucket.org port 443: Network is unreachable"

• Attempting to execute the following commands results in errors (we recommend you verify this to determine if you are experiencing this issue):
  

  > ssh -v git@bitbucket.org 
  "port 22: Operation timed out"
  
  > "GIT_CURL_VERBOSE=1 git ls-remote https://bitbucket.org/bitbucket/do_not_delete"
  "Hostname was not found in DNS cache" 

ソリューション

In case you are behind a firewall blocking IPv6 traffic, you will need to add our IPv6 addresses to your allowlist:

回避策

If you are still encountering errors after allowlisting our IPv6 addresses, then forcing the connection to use IPv4 can be achieved by adding the following line to your hosts file and attempting to connect again:
