The upload of the local file failed(Entity Too Large)

I rode a bike 300km on Zwift.
When I finished a ride, the upload of the local .fit file failed.

[21:59:34] NETCLIENT:Activity Upload: load fit file from path C:\Users\zuccha\Documents\Zwift\Activities/
[21:59:34] NETCLIENT:Activity Upload: fit file is length 1318895
[21:59:35] NETCLIENT:ERROR: RestInvoker: Unexpected HTTP response: HTTP Code: 413
<head><title>413 Request Entity Too Large</title></head>
<body bgcolor=“white”>
<center><h1>413 Request Entity Too Large</h1></center>

By server setting, file upload more than certain size seems to fail.

[11:08:50] Start
[21:59:34] Finish
I rode a bicycle for 10hours 50minutes.
(One hour of those is a break.moving time 9:40)

But .fit file data
elapsed time: 11:43:06
moving time: 10:33:44
There is a difference of one hour in an elapsed time.

Particularly, the latter part of data seem to large error.
Last few lap, I rode one lap in 9.5~10 minutes. But .fit file indicate 12 min.

hi - don’t have an answer to your question, but I’d suggest that you submit a request (top right hand corner of the screen)

just wanted to say well done for a 300k ride - nearly 10 hours on a trainer is amazing work.

(wonder what the longest ride is so far ?)

Thank you Simon.
Sorry for my bad English. I will try to submit a request.
