The new ui is working well if cerbo-gx is approached locally. Through VRM it does not work on PC, mobile, ipad etc. Wifi or 5G does not make difference. Error message: Error loading the WebAssembly.

Both in VRM and in the Cerbo-GX the new ui option is selected. VRM itself runs fine. Also the standard remote console works fine.

The cerbo-gx runs on v3.54.

Any ideas?

What browser are you using on the devices over the VRM?

Getting the same error. Sometimes with “Proxy relay not found”.  
With old GUI WORKS FINE!

Hi any solutions found? On LAN it works, classic ui through vrm also works. New ui on VRM fails with “error loading webassembly”. I get a 404 error (file not found) and a CORS error on venus-gui-v2-wasm.

any ideas please?

Yes, I fixed the issue by enabling Remote Support (Settings - General)

Other solution is to switch to the old Classic UI until they fix the issue.
