Do you run any other software? when you use Tor... the amount of connection and bandwidth could be an issue, maybe your ISP is playing with your connection.

So for my setup, I have a dedicated machine that is running two vms. One vm has mynode (which is the one with issues) and the other running umbrel.
I have had annoying power issues here for past few weeks due to a tornado that came through. We still have seen occasional surges. That likely has something to do with it.
Also I'm running a few miners and my house is notorious for tripping breakers. I think my electricity here is not the cleanest unfortunately. But I've had several instances of overloading a couple circuits and I think that could be contributing to the problem too...
That or tor is just finicky
