Observed Result

- Laptop takes forever to check update, and then instead: likely pulls full game from EOS due to timeout?

Additional Notes
This must be costing Epic SO much money in bandwidth.
Without reading your logs, it’s safe 2 assume 2 things are going wrong here:
- When resuming from sleep, EGL is taking too long to refresh.
- It starts checking for updates too early during this phase.
- It takes so long that it just gives up the checks.
- The checks now ignores whatever exists, and kicks off a full re-download instead.
This would explain why the desktops never have this issue;
I have sleep disabled on them: Windows always starts fresh, and EGL wont be opened until the OS has settled.
No Local sync is the second exacerbate: It might be time to look into BTS-style local-sync: Your CDN would already have “chunks” that it distributes, and I assume EGL just asks the CDN for each chunk…
EGL’s could/should also broadcast mDNS on LAN so other devices can learn they exist, and then those devices can simply pull any relevant chunks they may have locally.
