The update button inside the game just always says "no updates available". Yes, I verified that Options -> Other -> Enable Experimental Updates is still checked. Even tried unchecking just because. No difference.
Poking around where factorio updater gets it's info from seems to show that only factorio version 0.12.10 through 0.16.51 exist and only for linux headless at that.
I doubt this is the right forum to mention this issue since it seems to be a server-side problem and not an issue with the factorio client/updater.
BTW, noticed that https://www.factorio.com/download/experimental now contains the headless downloads too when there is the https://www.factorio.com/download-headless/experimental with the headless downloads. Maybe this recent addition/change unknowningly broken something? I'm grasping as straws
[edit]
Tried forums searching and google search but didn't have much luck. I'm sure now that I've posted this I'm gonna find a thread already covering this issue. Closest I've gotten is people on steam wanting to know why they didn't get 0.17.X
