Opensuse Leap 42.3 showing Connection reset by peer error when refreshing repos

Here is the screenshot of the problem:

When I look at that address with a boroser the file exists.

Maybe you should try again, or use another mirror.

BTW, I do not know why you think that making a screen shot, uploading it and showing it here is easier for you then simply copy/paste of the text from the Konsole window in between CODE tags of a post, but the latter is certainly easier for others to read.

As Henk said, try again…

“Connection reset by peer” is when a connection is forcibly closed by a peer. This normally results from a loss of the connection on the remote socket due to a timeout or a restart, typically under high load conditions, and is normally only transient.

If the “error” persists…

can you ping the host?
traceroute to the host?

No problem accessing that URL from here in the UK.
