I have a github actions workflow for deployment of magento application, while trying to deploy any change, the first run throws the below error, and when we re-run the failed job, it runs successfully, it has been happening for about 6 months now.
Below is the error log from github pipeline
https://repo.packagist.org could not be fully loaded (curl error 55 while downloading https://repo.packagist.org/p2/magento/language-pt_br~dev.json: Failed sending data to the peer), package information was loaded from the local cache and may be out of date

I had this error. It occures when you have the minimum stability in composer.json set at "dev" clear cache and switch over to "stable" and everything should work
