Upgrading from 7.0 to 7.1

Hello misc
Does somebody know how to solve this please:

Let's upgrade the sets!
Location of sets? (cd0 disk http nfs or 'done') [http]
HTTP proxy URL? (e.g. 'http://proxy:8080', or 'none') [none]
HTTP Server? (hostname, list#, 'done' or '?') [cdn.openbsd.org]
Server directory? [pub/OpenBSD/7.1/amd64]
Unable to connect using HTTPS; using HTTP instead.
Unable to get a verified list of distribution sets.
Looked at and found no OpenBSD/amd64 7.1 sets. The set names looked for
were:
bsd comp71.tgz xbase71.tgz xserv71.tgz
bsd.rd man71.tgz xshare71.tgz site71.tgz
base71.tgz game71.tgz xfont71.tgz site71-agrox.tgz

Location of sets? (cd0 disk http nfs or 'done') [http]

Note: After [http] there is one space. I did a new installation, and it
failed stoping the download.

Thanks
