We've been having issues with polling Hyper-V hosts with VMAN over the past year. After a couple of SR's with support we were advised to upgrade to 2022.3 (which was still pre-release at that point). We finally did that recently (actually 2022.4) but I had to manually hit the 'poll now' link for each host before they started working. Since then we had a similar issue with all the hosts in a cluster that was upgraded, and again polling stopped working until I hit 'poll now' for each host. Has anyone else seen this behaviour?
