Problems connecting VIC1457 to 91380YC-FX via SFP28 DAC

Anyone have any experience with this? Yes, we are using a 3rd party DAC. We tried a pair of SFP28 LR modules (both legit Cisco and 3rd party), and these came up after fiddling with the FEC settings, changing it to CL91. Cisco TAC recommended we either change to FEC Disable or CL74 to try get the DAC working. Still no link.

To note, I am running ACI vers. 4.2.3l
