[Mirror] Problems with mirror danweb2.dsteiner.ch on some machines

Hello everybody We got a strange behaviour on a Foreman server that won't load files from the swiss mirror danweb2.dsteiner.ch. The foreman server runs Alma Linux 8.x and is getting in to a timeout to the mirror above. Just to this mirror. It loads from other swiss mirrors (like mine: mirror.bf-net.ch) with no flaw. Other servers in our network (mostly debian based) are able to load files from mirror.danweb2.dsteiner.ch. So could it be a redirect not working good? Tested with curl or wget. Any help is appreciated. Regards, Urs
