[Ovmsdev] LoadProhibited exception on core 0

[Soko]

Hi guys,

Running happily my OVMS on my VW e-Up since 2020 it drives my crazy 
since today :(

It restarts roughly every minute with this status afterwards:
------------

Time at boot: 2023-07-03 21:25:07 CEST
This is reset #1 since last power cycle

And now the crazy part: It only happens when I'm connected to a specific 
WiFi/network?!?!

What I've tried so far:

 1. Factory Reset (multiple times)
 2. Set a static IP address
 3. Reconnect all cables and make sure all are snug and tight
 4. Brought OVMS closer to the AP (only one, no mesh)
 5. Restarted AP
 6. Restarted DNS & DHCP Server
 7. It even happens when I have no vehicle selected after a factory reset

It gets more crazy: My WiFi is via Unifi/Ubiquity. So I can have 
multiple SSIDs with the same AP. So all hardware involved is the same...

When I connect to SSID "E3200", which is network 192.168.254.0/24, the 
exception happens every minute or so.
When I connect to SSID "SurfHere" which is network 192.168.179.0/24, 
everything works fine!

Do you guys have any idea why this is happening?

I've tried to look at logs via Shell and "log level verbose" but nothing 
shows up. Is there more I can activate to log this issue?

Maybe my hardware is faulty... Where do I get a new OVMS here in 
Europe/EU/Austria? Do I have to import in from the UK 
(https://shop.openenergymonitor.com/ovms/)?

thanks heaps in advance,
Soko
