Firefox won't connect after waking from sleep, works after FF quit/restart
This is a somewhat recent phenomenon, but I'm not sure when it started exactly. But when I wake my Mac from sleep, all the tabs and windows just spin... won't load, or maybe load VERY VERY slowly (it seems like maybe a tab will make a little progress after a long wait, but never fully loads). I can fix it by quitting FF and restarting it - then all tabs load as normal.
There are several odd things that could be issues here, but I would think they'd be the same for both the laptop and desktop. I have a Mac mini M1 and a MacBook Air M1. I have no problems on the laptop, only the desktop. Both Macs are on the latest FF (86.0.1) and latest MacOS (11.2.3). Safari works fine... though I suppose I have to launch Safari to test that (I don't leave Safari running because I don't use Safari much). I have a Pi-Hole and I use several privacy plugins. I have DoH turned off on FF because I have it enabled on the Pi-Hole. But again... I don't get why the laptop works on wake but the desktop doesn't. They should be configured the same way.
How can I debug this? If I open the web console, would that tell me anything? Seems like it would just show that the network requests have no responses. From what I can tell by searching the web, there are no Firefox logs I can examine. So how can I debug this?

I found the difference, though I don't understand why this fixed it and would still like to know how I could have debugged this. On my laptop, I had not disabled DoH. So I re-enabled it on my desktop, and now it appears to be able to connect relatively quickly on wake. So first, why would that matter? Second, how could I have debugged this using networking tools (either in Firefox or outside of FF)?
