Bug description

Often to always failed when checking for Apps Update caused by very slow access to https://apps.nextcloud.com/api/v1/apps.json Connection speed on the Client and on the Server seems normal, but when accessing https://apps.nextcloud.com/api/v1/apps.json either from the server or from the client is pretty slow (mostly failed to load) for json file to be loaded completely.

1. Login

Checking update for apps completed successfully.
