Unable to authenticate System Field Programmable Gate Array (FPGA) or CPLD

Previously, my server R760xs suddenly powered off,  after that show notif on IDRAC, Unable to authenticate System Field Programmable Gate Array (FPGA) or CPLD either because of unsuccessful cryptographic authentication or integrity issue. Can this problem be solved with a cold reboot or any suggestion? thanks

Hello ArmanF, thanks for choosing Dell and welcome to our community!

 

ArmanF, I belive we need TSR logs for this: this error could be fixed with power drain, but TSR may have some answers what cause server reboot. 16G servers would most likely be in warranty, would you kindly raise a ticket instead when you have a moment? https://www.dell.com/support/home/en-us

 

Let us know if you have any further questions, we are happy to help.

 

Respectfully,

Hello ArmanF, did you get resolution to this problem? I have a server that is giving the same error.
