Thank you for your message.
Could you please let me know if your RU Server is updated to the latest version 18.104.22.168
as well? In addition, could you please clarify if you use RU Server as a sync server
only or if it also doubles as a relay server
? Last but not least, please let me know if you have any antivirus software installed on the machine with RU Server?
Looking forward to your reply.
