I am able to ssh into my droplet. Am also able to apt update and apt upgrade.

When I try to run sudo composer self-update or composer update, I am getting connection timeout error.

The "https://getcomposer.org/versions" file could not be downloaded: failed to open stream: Connection timed out

I tried to manually get a copy of latest composer but it also doesn’t work

output of php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

PHP Warning:  copy(https://getcomposer.org/installer): failed to open stream: Connection timed out in Command line code on line 1  

What could be the reason? I was all working till about a week ago. I am able to visit (browse) the webpages hosted on my droplet.

The issue seems to be regarding the ipv6 setup. I really have no idea how to make it right on Digital Ocean droplet. However by setting the ipv4 traffic higher priority than the ipv6 does seem to be a working - workaround the issue as explained on Composer website.

I got the sudo composer self-update and composer update(from within a laravel project directory on do) working after the workaround. The composer update still runs very slow even with ** php7.0 **. Nonetheless it works.

Hope it helps someone else in a situation like me.

I have the following issue too

The "https://getcomposer.org/versions" file could not be downloaded: failed to open stream: Connection timed out
The download failed repeatedly, aborting.

I believe there is an issue with DO networking or most of their IP get banned.
I can run those command in my machine.
