One satelite shows 90% online, ther others 100%

[Alexey]

No, it’s not normal. This is mean that this satellite was unable to contact your node.
You may check when it was happened:

My uptime should be 100% on all satellites i have not gotten any uptime robot notifications of downtime in months

Would you mind to provide dashboard from the uptimerobot? And also, please, provide result of the command: PowerShell foreach ($item in ((Invoke-WebRequest http://localhost:14002/api/sno).Content | ConvertFrom-Json).satellites.id) { ((Invoke-WebRequest http://localhost:14002/api/sno/satellite/$item).Content | ConvertFrom-Json).auditHistory.windows | Where-Object{$_.totalCount -ne $_.onlineCount} | ForEach-Object{Write-Host $item; $_ | Format-Table -AutoSize} } bash for item in `…

Then check logs of your firewall/router on those dates to figure out why is it happened.

You may also find some explanations in your node’s logs as well, search for ping satellite failed except rate.
