SharePoint 2013 Office web apps preview not working

Question

I am having issues with the preview of our sharepoint office documents, it is not working, i have checked the OWA Server and the owa services are running . I also checked the binding using Get-SPWOPIBinding and it returned the bindings to the owa server. I have also set the zone to external-https using

Set-SPWOPIZone –zone “external-https”

because i saw that the zone was binded to external-https in my sharepoint servers. but still the issue is still there.not sure why and I don't understand the ULS logs either. these are the ULS logs for the correlation id of one of the documents i was trying to preview.

Unexpected Exception in SPDistributedCachePointerWrapper::InitializeDataCacheFactory for usage 'DistributedLogonTokenCache' - Exception 'System.ArgumentException: Max connections value should be in the range 1 to 100. Parameter name: value at Microsoft.ApplicationServer.Caching.DataCacheFactoryConfiguration.set_MaxConnectionsToServer(Int32 value) at Microsoft.SharePoint.DistributedCaching.SPDistributedCachePointerWrapper.InitializeDataCacheFactory()'.

Token Cache: Failed to initialize SPDistributedSecurityTokenCache Exception: 'System.ArgumentException: Max connections value should be in the range 1 to 100.

i'm stuck and i need assistance.

However i dont't know if this is related, when i checked the site using the client laptop, there was a certificate issue (it was using a wildcard cert, different from that of the certificate i binded in OWA server and imported and installed in sharepoint servers) this is my first time handling certificates so i am confused where to start with the resolution.

Answer 1

i found a dumb mistake while testing. i was using the system admin account and it turned out that it will not work for OWA.
