I tried upgrading Magento CE from 2.4.3 to 2.4.3-p1 using the following commands:

composer require magento/product-community-edition=2.4.3-p1 --no-update composer update

but I am getting this error:

Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires magento/product-community-edition 2.4.3-p1, found magento/product-community-edition[0.42.0-beta7, 2.0.0, ..., 2.4.3] but it does not match the constraint. 

Any help would be appreciated.
