I'm running mainsail on my rpi 3a+, and have experienced network problems over a longer period of time now.
Frequently when I'm trying to open the web interface, the server is not online, and I think the pi is disconnected from WIFI. At least it doesn't appear in an Ip scanner.
I have googled the problem, and I have disabled network management. This improved the frequent network problems, as before it was offline almost every time I was trying to access it.
A wild guess is that the interface is online about 50% of the times I open mainsail.local.
I usually just have to wait it out to come back online. This usually takes about 1-20 hours, and will crash again at any moment.
I have tried disconnecting it from power, and letting it boot up again. But this rarely fixes the problem.
The server is offline at the moment, so i cannot attatch any logs. But I will happily send them when its online again. Which ones do you suggest sending?
