Hi Shawn, et al, I haven't thought about ip6. Interesting idea.
- I've tried to use the address 127.0.0.1. It did not help (I've un-commented the suppress-output-line in the script, so it is possible to see what it is being done) [1]. I also tried all possible combinations of the IP addresses that got assigned through the net cards without no success [2]. There is some 10sec delay between the start of the command and the error. - I also reset ip6v as you suggested without any success [3]. - ping returns in my case as in yours [4]. - ipconfig /all returns [5]. - Then I disables ipv6 on the network card. No change. - Then I found https://superuser.com/questions/586144/disable-ipv6-loopback-on-windows-7-64-bit and did [6]. No change. I restarted the cluster with -z 127.0.0.1:10999 [6]. No change. Any comments are very helpful. Cheers, Arturas References: [1] F:\solr_server\solr-7.2.1\server\scripts\cloud-scripts>f:\solr_server\solr-7.2.1\server\scripts\cloud-scripts\zkcli.bat -zkhost 127.0.0.1:10999 -cmd downconfig -confdir
