Prusa CORE ONE disconnecting from PRUSA CONNECT

Hi,
my Prusa CORE ONE is always disconnecting when downloading files to print. The printer connect itself to prusa connect with ease, however when I upload a file to printer it disconnects itself. After few minutes it connects back and continue the download.
Could anyone help me?

Hello, sinds a week I own a Core One and it printed like grazy everyday 24 hours a day but today 21 september it keeps disconnecting from Prusa Connect. I see I'm not the only one.

Having issues here, this was working fine a few days prior, on the latest 6.3.4 firmware. I checked the endpoint, and the certificate isn't trusted, the issuer is "Buddy Intermediate CA". Not sure if the internal firmware has the rest of the chain to establish trust, but there appears to be some issue here.

Attached is a SS of the error/issue.

I suspect that it appeared after some update. Have you recently updated your printer?
