Commit error: "Temporary failure in name resolution"

The last day I constantly get this error while trying to commit on Binder (filled in API, project name and files). Worked fine before.

ConnectionError: HTTPSConnectionPool(host=‘’, port=443): Max retries exceeded with url: /user/profile (Caused by NewConnectionError(’<urllib3.connection.HTTPSConnection object at 0x7fcc7a9f9c40>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution’))
