Help with updating Views module

When I tried to update Views module, I always had following error:

—————————————-
HTTP error -1 occurred when trying to fetch https://ftp.drupal.org/files/projects/views-7.x-3.18.tar.gz.
Downloading updates failed:

Failed to download views from https://ftp.drupal.org/files/projects/views-7.x-3.18.tar.gz

—————————————

Note that problem exists only for updating Views module. I have no issue with updating other modules.

I can easily download the zip file from https://ftp.drupal.org/files/projects/views-7.x-3.18.tar.gz., so there is no network connection problem.

Anyone know why this happen?

Thanks.
