Uploading problem to xojo cloud from linux mint last version


Due a problem ,with my mac book pro i purchased a pc with linux os (mint cinnamont 19)
I have last version of xojo web (2019r3)

So what is appening is that when im trying to upload the web application to my xojo server im getting this message:
“An error occurred while communicating with the Xojo servers”

What is strange is that i have also a pc with windows 10 , same xojo web 2019r3 and no problem at all when uploading applications.

What can be reasons?

Thanks for the help

If you haven’t contacted Xojo Support directly about this, you should. I can’t think of anything in Mint that would block a connection attempt. Also, its it possible that you are behind some type of firewall or a badly formed Proxy server?
