I have SharePoint 2019 farm (Two app servers internally and two web servers and OOS server in DMZ) and opened all necessary ports for firewall changes. Web application is working internally and externally and the OOS discovery site is loading both internal and external.

But the problem is opening documents in browser and getting error "Sorry, there was a problem and we can't open this document. If this happens again, try opening the document in Microsoft Word and with some seesion id: "

Getting the below unexpected errors in OOS ULS logs:
HttpRequestAsync, (Wopi,CheckFile,WACSERVER) no response [WebExceptionStatus:SendFailure, url:UREDACTED_(DTwOeq/v6RpQYEONxtJTM3p0xaQzXgD0bLU4blNakzU=)]

FileUnknownException while loading the app. [FileSourceId: -1088102096] [ClusterId: 0] [ExtraErrorInfo: ]

Tried to dig into this and over internet also, there is no clue on fixing this issue.
Getting this error while opening the documents both internal and external.

Can anyone help me to fix this issue please?

    Hi @Madhu Muppavarapu

    I suggest you run Get-OfficeWebAppsMachine to check healthy status first.

    Then please refer to 'OWA error: Sorry, there was a problem and we can't open this document', tryBenny Skogberg's suggestion.

    The issue resolved after enabling firewall ports for OOS VIP and SP web app VIP and between OOS and SP WFE servers.
