SharePoint 2019 excel online files will not load

Question

Our old certificate recently expired.  I ran the following command on our Office Online server:

New-OfficeWebAppsFarm -InternalUrl "https://spservername.domain.com" -CertificateName "*.newcertificatefriendlyname" -EditingEnabled:$true

• excel documents would not load so i ran the below code:  

$Farm = Get-SPFarm

$Farm.Poperties.Add("WopiLegacySoapSupport", "https://sharepointserver.domain.com/x/_vti_bin/ExcelServiceInternal.asmx");$Farm.Update();  

after restarting servers. still same result. excel online just loads. never times out but will not load

Answer 1

1.Run this PowerShell Get-OfficeWebAppsMachine to return the health status of your Office Online Server.

2.Remove all WOPI bindings from SharePoint farm then recreate with PowerShell command.

Remove-SPWOPIBinding -All:$true

New-SPWOPIBinding -ServerName <WacServerName> -AllowHTTP

3.Find clues in the ULS logs.
