on my dektop with home internet a few days ago I tried to sync a new profile’s cards and got Error details: error sending request for url (): connection error: An existing connection was forcibly closed by the remote host. (os error 10054)""
the advice I found on here was to try a different internet connection, so I got on my laptop and used my phone connection. This worked to download the cards into the new profile, but when uploading I got, if I remember correctly, a 10056 error (not 10054). later I tried again using mobile and it worked.
about desktop / home intenet
I switchedf off then deleted the add-on VPN I was using the computer, but this did not help. I have had the VPN for quite some time and there was never an issue before.
Of interest is that at first, after I encountered the 10054 with the new profile on my desktop, I entered an existing profile that had decks on the desktp already, I added a subdeck to this other profile and a new card, and it synced successfully without a problem . However, after a few days even the existing profiles run the 10054 error when I try and sync them
I can use laptop and mobile top sovle problem of desktop not syncing, but it would be more convenient if someone knew how to overcome the 10054 poroblem without switching to a different internet connection
