Figured it out. I had "Internet Access" enabled, which automatically allowed the ISY to respond to port 443 without port forwarding. Seems that the log entries were indeed external login attempts.

Found a bunch of these in my error log seemingly from various IP addresses. Are these login attempts? Are they from Mobilinc? I have port forwarding turned off on my router, so I don't really understand how they can be login attempts, yet the port 443 indicates that's exactly what they are.

Latest: I unchecked the "Keep temporary files on my computer" in the Java console. That seems to have fixed it. Now it's working properly. I can open the admin console without clearing temporary files.

I reinstalled Java, and it's now working again. But I still can't run the admin console twice without clearing Java cache in between. That's not a power supply issue or an SD issue. This is some sort of Java issue.

Running Tahoe 26.7.1 So I just tried deleting all the ud_ files, and now I can't fire up the admin console at all. Launcher recognizes the IP of the ISY, but the Type and Version are again blank. Tried restoring the deleted files - doesn't work. I'm now dead in the water again.

Tried the above. So far, nothing I've tried has allowed me to fire up the admin console twice without clearing the java cache in between.

Interesting follow-up: Seems I have to clear the Java cache every time I want to load the admin console. If I don't clear the cache, IoX Launcher displays the URL/IP of the ISY, but the Type and Version fields are empty. If I then clear the Java cache, everything is back to normal. Why would I need to clear it every time? This is recent behavior.

Thanks for the suggestion on reinstalling Java. That fixed it. As for why other things weren't working, and why it came back piecemeal, who knows. Back when I was a practicing electrical engineer, when the unexplainable occurred, we would just say "Must have been a blast of EMI" and move on.

Yes, it works via port forwarding from the public IP. Yes, I'm sure its on the same LAN. As for your suggestion that my computer might be on a different WAN, the answer is no. The MacBook and ISY are both connected to the same LAN. The IoX launcher shows the LAN address of the ISY properly, but I can't click on it to open via the LAN. I have to manually add the WAN address and open it from there. Yes, I can ping the ISY on the LAN. Port forwarding wouldn't work if I couldn't. Not sure I agree with the "something is wrong with your router" suggestion. I've got dozens of devices on my network that are all working fine.

This setup had been working flawlessly for the past 10 years. Something must have changed, but I don't yet know what. As I said, I've been able to gradually get it to the point where everything now works except for the ability to log in via the LAN. Yes, I found the LAN address in the admin console, but it won't open that way. It only opens by using the WAN side IP of my router.

Things are working gradually. I managed to get in to the admin console by using the WAN address. It won't load using the local network address. But I'm making progress here.

I've been trying a few other things. 1) Pressed the device reset button, and after a few minutes, I was able to read and change variables via Mobilinc. I also was able to test that the variables are readable by IFTTT. But it still won't control devices nor can I log in to the admin console. 2) I tried replacing the PLM with a spare. I'm now able to see the status of my Insteon devices, but I still can't control them. When I walk over to the switch and manually turn it on or off, Mobilinc can see that the state changed. But controlling the switch doesn't work. And still can't log in to the admin console. 3) Put the old PLM back in, and I regained control of devices. Almost everything is now working. But I still can't log in to admin console. Any other thoughts before I try a factory reset?

Hmmm, easier said than done since I don't have a spare power supply. Anything else?

No joy. Anything else?

So this is a little confusing. My ISY is no longer responsive. Programs don't run. I can't bring up the console. However, when I open Mobilinc Pro, I can see that according to Mobilinc Pro, the state variables show a last updated time that corresponds with my most recent power cycling. So that implies that Mobilinc is somehow able to see what the variables are and somehow knows the ISY was power cycled. I've tried with and without the PLM. I've tried power cycling several times. I've tried rebooting my router. Any other suggestions on what to try before I throw in the towel?
