Connection timeout error while updating composer on Digital Ocean

Question

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 droplett. Am also able to apt update and apt upgrade.

Solution 1

https://getcomposer.org/doc/articles/troubleshooting.md#operation-timed-out-ipv6-issues- could solve your problem. And if composer update is slow afterwards, try running it with a more recent PHP version. Running it with PHP 7 instead of PHP 5 will cause a big speedup

Solution 2

You can run this command as root to make IPV4 more prior than IPV6:

sudo sh -c "echo 'precedence ::ffff:0:0/96 100' >> /etc/gai.conf"

Have a look at getcomposer.org/doc/articles/… - this looks like your problem

[Donkarnash]

@NicoHaase This seems to work - atleast get the sudo composer self-update worked. However the composer update within a project directory is pretty slow - seems to take ages to update the dependencies. I think I will have to google further to understand why the composer update is so slow. Thanks again the issue does seem to be about improper ipv6 config on droplet. If you post it as an answer, I'll be glad to mark it as correct answer.

Thanks, all morning searching for this. It's some sort of problem with my network «I guess» so I don't have access throw ipv6 but it works on ipv4. Thanks Bro.

Can you explain that further? How does composer diag solve any problem?

[JessGabriel]

I don't know what really happen but sometimes it resolves the problem. Looks like composer diag don't diagnose only but trying to solve something or change something too
