Web server appears to have stopped working

[adam-griffiths]

I've been using my IMSAI more than normal this last week. This morning I've attempted to use it again but no matter what I try I cannot get to the web interface.

I've attached it to my Mac and get the following when I boot it up over serial, running brings up the command line for CP/M.

I've tried to reset it by entering the config again using the following: 0000 1001 0101 0100 which I believe is the right command with 3 high for using it as a device to browse to rather than as an access point. The config is the same as it was last week.

Any ideas anyone?

EDIT: Fiddled around a bit more and putting it in access point mode I can get to it, but only on my Mac, not with Linux. Putting it back into WiFi mode I can see it on my network. But browsing to the ip address, it just stalls.

Often clearing cache and cookies resolves this for me.

Tried that - nothing. Even went so far as to install chrome on my MacBook to try a new browser and it didn’t work. I’ve updated the firmware and created a new SD card with the latest version on it. I can now reliably access it as an access point every time. Editing the config for my network I can see the IMSAI as an available device on my WiFi network, but when I try to browse to it, nothing. Http://ASSIGNEDIP/console should work right?

You shouldn't need the /console on the URL.

Tried it without to no avail. Turned logging on again and got this:

I must confess, networking is not a skill I have under my belt, but trying to understand it, it looks as expected. And should be available at 10.0.0.46 but it still is not. One thing that doesn't look right is that although I am declaring it's in NZ, there is this line: Access Point: Country = AU. Which I would assume should say NZ now?
