Using the API will probably not solve your problem as the data package you want to download is quite large. This means you will not be priority for the system. Less large downloads will be given priority. So if it is possible for you to download the data piecewise, do so. Regarding the authorization error: https://cds.climate.copernicus.eu/api-how-to could help.

Sure thank you I now know it may probably be the network problem, so therefore I would ask for someone else's help. Thank you.

What details can you provide? If I recall correctly, accessing ERA data requires login information.
