DraftXR: Draft not publishing

When i try to publish my draft on Adobe Xd with DraftXR, it gives me the following message:

"DraftXR failed to create the draft. Make sure you are connected to the internet. You can try reloading the plugin the using shortcut..."

When I check in the plugin developer console, the logs show a 413 response code error. Sometimes, it shows me a 504 error code instead. 

Could I get some help on this?

I have tried reinstalling draftXR several times.
