Multiplus II GX 5kVA webinterface fails after update

Last week I updated the Multiplus II GX 5kVA to the latest firmware, today I tried to connect to the venus.local web interface and got this screen.
The thing seems to function OK, charging and inverter function, but I would like to see what is going on.

You can try the old one (v1) http://venus.local/gui-v1/

It is not the solution

Do you have any modifications loaded on the GX?

Not modifications, only two assistants, one for limitation on AC current from grid, and one for limitation DC charge current.
And a very small Node Red configuration to limit the charge current based on the SOC of the battery.

I tried V1 yesterday, and yes, that version is working.

Yesterday I updated the firmware to the latest version (via the V1 interface) and hurray! it is working again.
Strange hickup
