Starting with about 24.01.2022, I experience troubles with updating OS. Previously there were troubles with getting files with repository description, such as https://download.opensuse.org/reposi...primary.xml.gz.

Today I cannot get updates at all:

"Error with loading" (curl) "https://download.opensuse.org/reposi...3.2.noarch.rpm":
"Error code": Connection failed
"Error message": Could not resolve host: mirrorcache-eu.opensuse.org

I am using https instead of http, that means using "mirrorcache.opensuse.org".
Trying to change https to http for Packman with YaST: unable to do this.
I can download files with Firefox, but during update system cannot see them.


Reports during getting update description files:

1.
