RPM download mirror times out - offline mirror

When trying to upgrade my system I am getting:

Timeout exceeded when accessing 'http://download.opensuse.org/repositories/devel:/languages:/nodejs/openSUSE_Leap_15.0/x86_64/nodejs8-8.12.0-lp150.88.1.x86_64.rpm'.


It seems, for this download, I am being redirected to: http://mirror.tspu.ru/opensuse/repositories/devel:/languages:/nodejs/openSUSE_Leap_15.0/x86_64/nodejs8-8.12.0-lp150.88.1.x86_64.rpm

Why the download server redirecting to unresponsive mirrors? What can I do to avoid being redirected to this broken mirror in Russia (there should be way closer ones to me)?

Replace the failing repo’s URL by a mirror nearby your location. See https://mirrors.opensuse.org/list/15.0.html
