Unable to load a course on fenix 5x, constant "An error occurred with your upload. Please try again".

I've tried numerous avenues to get a course installed or, loaded including manually installing course inside the folders of the watch GPX, newfiles and both GPX file and TCX files. Nothing seems to work. Watch shows that I'm connected via bluetooth and I'm connected with the USB cable. Files came from Alltrails.

Thanks for your help
