Excel is not opening after configuring WOPI integration in windows server 2012 r2

I am working on a WOPI integration project to enable web based viewing / editing of office documents using office online server. After configuring MS-WORD and PPT files are working fine but facing problem while opening Excel file online. From WOPI logs I get the following exception.
Exception:Unhandled Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.InvalidOperationException: This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms.
at System.Security.Cryptography.SHA256Managed..ctor()

After getting this exception I did some research online and get one solution.
Solution-Link:https://www.ibm.com/support/pages/implementation-not-part-windows-platform-fips-validated-crytographic-algorithms-error-launching-controller
After applying the above solution also I am unable to open the Excel file online. Please find the attached logs and please provide solution on the same.88910-excelservicesecswatchdog.txt




Thanks in advance

Please refer to "This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms when building an app with visual studio", delete the FipsAlgorithmPolicy registry entry to instead of enabling it to check this issue.
