I just made a bunch of changes to my project, and it will not save (I have been able to save earlier in the day). I get the "Uploading to gateway" progress bar, but it eventually times out with the error below. The clients that are running are working fine.

Well, that error is a symptom of the timeout while saving, not a cause. Something is causing the save operation to timeout, possibly on the Gateway. Check the Threads section of the Console area of the Gateway config section, perhaps there is a deadlock? ---

I restarted the gateway and it snapped out of it for now. Looking back at my notes, it acted very similarly to another problem I had on Apr 29th, so it must have been another deadlock. I couldn’t start the gateway home page, so I couldn’t do a thread dump this time. I had previously updated to 7.2.5 after the Apr 29 event, but your notes say that 7.2.6 should resolve this problem, so I’ll have to schedule that update after I test it on another machine first. ---

Yeah, a deadlock would be my first guess for that behavior.
