Updated some robots in the field to 5.11.5, and now once in a while the play button stops working. I had to open a virtual terminal and telnet into the dashboard server to send play/pause/stop commands. Restarting the robot would temporarily fix it.

Robot: UR10e  
SW: 5.11.5

The only thing I can think of is that the new software doesn’t like an old URCap based on reading some of the terminal logs:

That looks odd, but it’s not enough to diagnose.  
Press e-stop right after you can’t play program - that will generate error report. PM me, or better your tech support with “support file”
