In Resilio Management Console UI you may notice 1 Error status for a client that expands to Excessive Time Difference.
This error means that the UTC time difference between Management Console and this agent, or between the agents in a job, is more than the allowed window of 600 seconds.
Check time, time zones and dates on the Management Console and Agent machines and compare results - they have to be the same:
OS X/Linux in Terminal:
Windows in Command Prompt:
for /f %x in ('wmic path win32_utctime get /format:list ^| findstr "="') do set %x
Run the command with minimal time lag to get more accurate results for comparing.
Once the time is the same, restart Resilio Connect Agent process.
