I migrated the configuration to Floxum, and there is no reference to flarum.org anywhere in my composer.json and auth.json. It worked initially, but I noticed that the deployment fails even though it works locally. It only worked because of the cache. After running composer clear-cache, it stopped working.
Error: The "https://flarum.org/composer/archive/blomstra/realtime/0.3.3.0.zip" file could not be downloaded (HTTP/2 404 )
In CurlDownloader.php line 668:
The "https://flarum.org/composer/archive/blomstra/realtime/0.3.3.0.zip" file could not be downloaded (HTTP/2 404 )
I also removed the vendor directory and composer.lock. It still tries to download blomstra/realtime from flarum.org, so something doesn't seem right on Floxum's side.
