    @Cygace Someone from the community may jump in and help troubleshoot this. The best approach would be to not modify the Dom0 installation by installing Zabbix via a community post, as you're customizing the installation. The vates team and XCP-ng specifically need to include these packages to ensure you're able to get support. Best of luck

    I did stick to version: 1 in my working configuration [image: 1757959695876-01998ae9-bb3f-4a3c-b3f6-b1d34ae23704-image.png] Had to rename my "Ethernet 2" nic name to Ethernet2 without the space You have to put the exact template nic name for this to work.

    That's the issue. Why they don't have it is the problem/mystery. Try to check if new replicated VMs got it. If not, I would check if you are correctly up to date.

    @joearnon The browser javascript logs may give you useful information about what issue happened during the import as seen from XO's side. However the disappearing SR issue makes me think you should look at XCP-ng logs, in particular /var/log/SMLog for storage-related logs and /var/log/daemon.log.

    @olivierlambert You inadvertently solved this one, too, n parallel with @tony . So, basically, as suspected, a template is nothing more than populating stuff that's in the basic and advanced webforms on Orchestra, anyway.

    There's a 1 min cache on XO's side. So if the updates weren't showing up for more than 1 minute, then it might be something else.

    @olivierlambert said in Backup failure: HTTP request has been canceled: It's a problem when XO tries to get address from your srv02.xxx.com. It just makes no sense that DNS would be an issue on this network. I guess if XO momentarilly looses connection during DNS lookup it could cause this problem. I've noticed sometimes that the webui of XOA sometimes can show red ? if I start live several live migrations. Maybe unrelated?

    @thorcraftit seems like perhaps a permissions error, what does your share properties on truenas look like for this host? Is the allowed IP or denied IP boxes populated at all? Attach a screenshot if you can. Here's what mine looks like: [image: 1625573743330-f76ebeef-c5cf-452e-8a43-28144d9a8c94-image.png] Note that the mapall user and group must have permissions on the shared folder, I typically create a user on the freenas system just for xen shares, and give it ownership of the folder/dataset that's being shared. this ensures you don't have any weird permissions issues. I think in your case the key boxes to examine are the authorized networks however. What does your Services > NFS > Settings look like? here's mine: [image: 1625573851182-3ccf191c-575c-4094-b91f-b4e12e6a4091-image.png] Lastly and perhaps most importantly, can you run "yum install nmap" and then "nmap 172.16.60.200" on both a working host, and then this non-working host? Paste the results of both here - if they differ, for instance if the non-working server doesn't see any RPC services running like I suspect, that will heavily point towards a firewall/network/ACL issue

    That's because of XCP-ng/XenServer design. The host isn't pushing data, it's only exposing an HTTP handler to pull from it. You can use XO Proxies if you prefer: https://xen-orchestra.com/docs/proxy.html

    @darkbeldin Thank you. That was just off the bottom of the screen and I did scroll past it a few times, but being a little lonely icon, when all the other items have text, it didn't even register as a thing!
