After some time I tried to use NcSyncServer again.
Environment is
Server Ubuntu 20.04 - NCP Version 4.7.6
only accessible with SSL / HTTPS

Client Ubuntu 22.04 - NCP Version 4.76

I can start NcSyncServer without any error in the terminal.

When I test the connection in the client I get a "SSL Handshake Error" with the first attempt and a "Read error" when I try again. The pattern continues with any further attempt.

Anyone any Idea? I am not a security expert and usually I sync using Nextcloud but for one of my clients I canÄt install Nextcloud - hence trying to reactivate NcSyncServer ;-)

Thanks
Raimund

Hi Raimund,

thanks for the report.
It could be that server and admin use different versions of OpenSSL or some protocol version is not supported anymore, would need to check.
Are both sync server and sync admin started from the same PC?

Regards,
  Miro

I've tested on Fedora 39 and things work fine here:
  • started both sync server and sync admin within the same VM, each in its own terminal
  • used default admin password ("notecase")
  • connection succeeded, no crash
I plan to download, install and test with Ubuntu 22.04, but I still need the answers to my previous email.
The more details I have, the better.

Regards,
  Miro

Tested on Ubuntu 22.04.03 as well, both server and admin running in the same VM, all works OK here (logs from both terminals below, SSL read is due to closing admin app).

I deleted the server installation of NoteCase Pro and re-installed it on the server - what can I say - now it works again.
No idea what happened.

Thanks all for your feedback!

best regards
Raimund
