I freshly installed Nextcloud 24.0.4 with PHP 8.1 under Debian 11 with REDIS in a VM (8GB RAM) on Proxmox. One week ago I synced all files from my windows 11 laptop with the sync client to the (empty) nextcloud and it worked perfectly. No errors and super fast.
Yesterday I built my new windows 11 desktop PC and it is works really good except the nextcloud sync client. After downloading ~1GB of data, I get this error message:
Error while reading: error:1408F119:SSL routines:ssl3_get_record:decryption failed or bad record mac. When I force the sync again, it works for some more data but after 1 minute again the same error.
Downloading over the web interface works really good (100MB/s download and upload even for large files (5GB)). So I guess it is something about the client. But on my laptop and on my desktop is version 3.5.4 installed and it works on the laptop but not on the desktop
Right now the nextcloud server is not publically available, so I’m using snakeoil certificates (created by
openssl req -x509 -nodes -days 365 -newkey rsa:4096 -keyout /etc/ssl/private/nginx-selfsigned.key -out /etc/ssl/certs/nginx-selfsigned.crt and edited the hosts file on my desktop pc and on the laptop. Again: In the webbrowser on both devices and on my laptop with the sync client everything works fine, but only in the sync client on the pc it doesn’t work.
I also reinstalled the sync client multiple times and deleted / the account but still, the problem exists.

Thank you for some ideas!
I now updated to 3.6.0 RC1 (released 3 days ago) and the problem still persists
