@Divo You would want to adjust your script to disable the smb share or put it in maintenance mode prior to shutting down. I ran into an issues for when I was shutting down a Remote just to save power - https://xcp-ng.org/forum/topic/12339/xo-unresponsive-when-remote-storage-is-offline.?_=1791151494204 It still didnt help with the unresponsivenes. This was with a Backup Remote not a SR but enabled maintenance mode before shutdown and disable when back online.

@GregBinSD said: Here are two more notes regarding the XO6 "Unable to connect to XO server. Retry" message, which pops up after 30 seconds. It occurs when either the Chrome or the Microsoft Edge browsers are used on my Windows 11 PC. However, I often use a Samsung Tab-A9 (tablet), and it does not have this issue with XO6. It uses the Chrome browser. To enlighten you the Microsoft Edge your talking about is not the original release (from Windows 10). It’s the Chromium based release from during Windows 10 and has been that one ever since. The original release of Microsoft Edge had its own rendering engine called MSHTML. The current modern Edge effectively shares a common upstream code base with Google Chrome, namely Chromium. The Samsung Tab-A9 doesn’t have the issue even though it, uses the same browser namely Google Chrome. This is the case because the tablet uses a version of Google Android, which has its own kernel, which is a fork or variation of the Linux Kernel.
