OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible
OctoPrint version: 1.5.2
Python version: 2.7.13

Server: Raspberry Pi 3B (no undervoltage indicator)
Client: macOS Catalina / Google Chrome 87.0.4280.141 (official build) x86_x64
Printer: Prusa i3 MK3S+, assembled December 2020
This problem has occurred at least a dozen times in the past week. This same RPi ran an earlier Prusa i3 MK3 for a year, largely, without incident, and also has run this printer pretty steadily for four weeks before showing this issue. Nothing has changed in the past week, as best I can tell.
I looked for earlier posts that were similar. The closest I found was this one:
...which appears to be a different problem: I can SSH into my RPi from the client machine without any problem, and the web interface still hasn't updated for eight hours (even though the RPi is still running the printer A-OK).
