Thank you for your message.
This issue seems like it might be caused by an external factor, such as internet connection or firewall settings.
Could you please send us the following log files:
1. The most recent Host log file
2. RU Server logs
3. Viewer logs
We will examine the log files to see if there’s anything that might help in identifying the issue. You can send all logs to support@remoteutilities
Looking forward to your reply.
