### Summary This issue is consistent but only occurs in one of our projects. We tested it from multiple team member PCs to no avail. Unable to perform Memory Calculation due to Error. Error: “Encountered unexpected content beacon connection failure” ### Please select what you are reporting on: Unreal Editor for Fortnite ### What Type of Bug are you experiencing? Memory ### Steps to Reproduce Launch Memory Calculation in ### Expected Result Standard Memory Calculation ### Observed Result Error: “Encountered unexpected content beacon connection failure” ### Platform(s) PC ### Island Code 1919-8086-5903 ### Upload an image ![UnrealEditorFortnite-Win64-Shipping_TUrQ10BPXV.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/b/4/b/b4b761202b7add3fd6e2dd224b3aaf02cac907c9.png) ### Additional Notes Can happen during Push Changes as well. If in the meantime, Epic could help us at least get the memory calculation to run on their end (on the latest game version) that’d be wonderful so we can push the update to players. Thank you! ---
