Bitbucket install fails with No route to host

[Wolf Schwurack]

When I try to install Bitbucket using #./atlassian-bitbucket-7.20.0-x64.bin

 repeats this message

2022-02-28 13:20:58,925 INFO [Thread-4] o.a.http.impl.execchain.RetryExec I/O exception (java.net.NoRouteToHostException) caught when processing request to {s}->https://www.atlassian.com:443: No route to host (Host unreachable)

I have tried to set the proxy before running the command but still fails with message

export http_proxy=http://p.uen.org

export https_proxy=http://p.uen.org

export HTTP_PROXY=http://p.uen.org

export HTTPS_PROXY=http://p.uen.org
