How to reliabily program multiple FPGAs using quartus_pgm?

I have a server with 8 x Stratix 10 SX boards (Terasic DE10Pro), which I would like to be able to program over usb-to-jtag. When I have one or two baords installed, I can reliably program a board, e...

There's a general problem when working with multiple programmers connected to one PC (= one JTAG server). Establishing the connection to a programmer can fail if another programmer is active at that time. Connecting all programmers first and than starting activities should work.

This might be a problem with the intended command line operation but it works in GUI operation of multiple programmer or debug tool instances.

Thanks for confirming that you have also seen difficulties with multiple programmers connected to one PC.

I did try the GUI for programming, but this didn't improve programming reliability; I see the same behaviour. I am only programming one FPGA at a time to avoid any issues with jtagd struggling with parallel clients.
