Documents aren’t displayed in web browser due to TLS
When you use web apps in Microsoft Office Online Server, documents are not displayed in the web browser as expected. Instead, you receive an error message that resembles the following:
We’re sorry, we ran into a problem completing your request…
Additionally, you learn that TLS 1.0 has been disabled on the SharePoint web front-end servers through the registry
To Resolve this make changes in the registry
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319] “SchUseStrongCrypto”=dword:00000001 [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319] “SchUseStrongCrypto”=dword:00000001
