Unhandled object exception:

ExceptionSubClass:0
Then gives Error in sending and/or receiving messages over http 400
The following message details is following
{"data":{},"status":400,"config":{"method":"GET","transformRequest":[null],"transformResponse":[null],"url":"portatech104.isiusa.local/.../0","headers":{"Accept":"*/*","T":"raQYcIe7w1yBWTOW1KQFGw=="},"responseType":"arraybuffer"}}

This is test machine client and server on same machine. I can see the .temp file on C:\ProgramData\Microsoft Dynamics\GPSessions\Data\wvwybadt.0ds_14944\Temp
Any help?
