Data Model Publish got 404 error

Team if any one of you facing the similar issue please share how to resolve this issue
I have two environments Test and QC, 
1. Create new data model  (using live snowflake conn) with 2 dashboards in Test environment.
2. Export smodel from test and import to QC, Successfully published the model.
later had some modification in data model in Test, upon successful validation and export *.smodel from Test to import to QC, while import to QC is successful but i can't publish this data model got the following error

Error while running action: Unexpected error value: { isOperational: true, message: "Request failed with status code 404", code: undefined, statusCode: 404, method:

But when i rename model to different name then its working and able to publish in QC.

If you any one have the solution please let me know, 

thanks!
