For a couple of weeks I have not been able to connect to the OSS and Non-OSS repositories - all my repository URLs are correct and enabled. When I went on package search and tried to download a package from the OSS repository, I could not because I could not connect to the OSS repository. I have searched for a thread which mentions this issue but cannot find one.

Hi
The repo type has switched, need to be of type yast2 not rpm-md…
Hi
there have been a few forum posts about this, fallout from the Maintenance outage…
See https://lists.opensuse.org/opensuse-factory/2017-10/msg00700.html
I appear to have found a fix by changing
http://download.opensuse.org/distribution/leap/42.3/repo/oss/
to
http://download.opensuse.org/distribution/leap/42.3/repo/oss/suse/
and the same for the non-oss repo
Fixed the problem by changing to https url. Opensuse site uses https, indeed.
