If I fiddle with mods, enabling/disabling some mods, then I'll likely get it working. And then from past experience it is extremely fragile - as long as I touch nothing, it will stay working, but if I change *anything* (upgrade a mod, remove a mod, upgrade Factorio, pretty much anything), it will get back in to this state where if fails quickly after connecting with “Service is not responding”. If I restore the server Factorio app, mods folder and map from a backup, it will go back to working. Change anything and it breaks again. So it does not feel like a situation where it's actually caused by the network or computer speeds (there is no reason a Factorio app update or removing a mod would make that difference).
This is the console messages on the server when this happens:

I've attached the factorio-current.log from the client, which shows it going astray with:

(and then lots more UnparsedNetworkMessage messages)
I'd love to figure out the cause of this since it's reoccurred pretty much every time I've set up a network game - I get it working, play through the whole game (eg Space Exploration, Nullius or Krastorio), but once started I cannot touch anything without this behaviour resurfacing, so if there is a mod update or a Factorio update, we just have to avoid the update until the game is finished.
Current mods for this game are listed below, but again, I don't really think it is an issue of a specific mod, as I get the issue with each different set of mods. Maybe one of the QoL mods since they might be consistent across the different runs, but most of the mods are not consistent, and again, I can get it working with the QoL mods, just after some random fiddling around, enabling/disabling mods until it works.

I've also attached the server settings, since they tend to be consistent between games, and its possible something in there could be the issue. I normally use non_blocking_saving, which I've never had any trouble with, but I turned it off just in case that was an issue, but that made no difference.
Thanks for any suggestions as to where the issue might really lie, or how to resolve it.
