I have not seen that.  My advice would be to open a support case for engineering review.  #IWork4Dell
Hello, I have a problem with some Wyse 3040 year 2020, following the migration to firmware 511, the reboot no longer works, I have to turn off the thin client to restart it. However, other Wyse from the same year are working perfectly after the migration (same group, same settings). If I downgrade to version 017, the reboot works ??? Any explanations or solutions to offer me? Thank you very much
PROBLEM REBOOT WYSE 3040 (2020) AND 8.6_511 OR UNDER
