X90CP174-S1 Ethernet not booting

Hi community,
thought I put this out in the forum in case somebody has come across this as well and has figured out a reason.
I am using a X90CP174-S1 very successful on several projects for several years.
On a latest project I came across the following strange problem…
Occasionally it happens, that during a download, the connection to the X90 terminates and does not restore - even after power OFF/ON.
The X90 is not reachable anymore - no connection, no ping
The only way to bring the X90 back into a reachable state is via an initial USB install (force initial installation).
I have been running uncounted tries to be able to replicate the issue and it shows a significant accumulation of this event after a date change of the RTC of the X90.
Has anybody come across the same phenomenon yet?

Hello,

can you send me a system dump of the affected controller?

Regards

Stephan
