This is a new one on me. I’m setting up two identical laptops for a client and 2nd one says it won’t upgrade to W11. So, I went to look at the CPU in the first laptop and it wasn’t listed in SimpleHelp. In fact, for this particular client only three devices are shown: ![image](https://community.simple-help.com/uploads/default/original/1X/46abbcf5781fb2c7954b86a34c2bd8db0197470b.png) Fortunately, all backed up so restored last night’s backup and they’ve come back: ![image](https://community.simple-help.com/uploads/default/original/1X/5e717af5222eaa8bb74caca93224c53574a25284.png) Any ideas? Auto forget is set at, what I think, is the default of 365 days. ---

My one thought is that I notice on the backup you restored that all the machines except for the “REV014” are showing gray (so offline). Did you check this to see if it’s the culprit… ![image](https://community.simple-help.com/uploads/default/original/1X/3c62c96c2afd575c013d61435e9f530cf2135809.png) ---

They’re mainly offline now because it’s evening in the UK. Yes, I’ve checked that. It’s set to a year/365 days. ---

Did someone accidently hit block on a bunch of machines? Might be worth checking if any are on the list from Login Security, IP Address Blocks ![image](https://community.simple-help.com/uploads/default/original/1X/603e904d0bb802104ca119c7d1c2008bac4ea5fd.png) ---

I noticed after updating to 5.3.3 ? that anything [HTTP://yoururlhere:443](HTTP://yoururlhere:443) doesn’t work anymore. but using https without the port 443 works. ([https://yoururlhere](https://yoururlhere)) Not sure why mine was originally setup to use HTTP and then port 443 but it was and those clients using it stopped connecting. ---

I think will chalk this down to “one of those weird things”. Hasn’t happened since restoring the backup of the configuration folder. ---

This has happened again! Computers have gone missing… about to restore a backup. ---

Restored last nights backup and they’re all back… weird!
