Ok thanks.. I will check your sequence..Hi Paolo,
I think I may have a clue. After seeing your message above I tried uploading to Strava from every different place I could find and did manage to get a couple of uploads to succeed (see attached) although I can also reproduce the same failure at will. The two times it worked were from the ride list when I selected the button to upload to Strava it prompted me for a ride name and I replaced the default text some something else e.g. "foo". All of the times it fails it does not ask me for the ride name. It just goes straight to the error dialog after pressing the upload button or first asks me to confirm that I want to upload it to Strava and then goes to the failure dialog. (Maybe it thinks those rides have already been uploaded so doesn't ask for the ride name?). Note that the error happens whether I press the button that is at the bottom of the screen that appears immediately after selecting a ride from the ride list or if I also press the "More Details" button and then scroll down to the bottom and press the upload to Strava button there. Similarly, immediately after finishing a ride and saving the gpx file, when it prompts me if I want to also save it to Strava if I answer yes it fails there as well.
So basically if the ride has not been named and it asks me to name the ride after pressing the "Upload to Strava" button it seems to work. But sometimes (most times) after pressing the "upload to Strava" button it goes straight to the error. Note that the error sometimes shows up before the confirmation dialog that asks if I want to upload to Strava, and sometimes afterward. If the ride has ever been previously named (or renamed) I can't get past the error.
