Did you try the latest stable MicroPython build?

{If this is seen as a 'highjack' then please let me know and I will open a separate dedicated Issue.}

I have the 'same' issue, but with a different target microcontroller and different browser client.

I am using a Raspberry Pi Pico W, running the 'stable' 1.23 release of MicroPython -

MicroPython v1.23.0 on 2024-06-02; Raspberry Pi Pico W with RP2040
Type "help()" for more information.

My client browser is Microsoft Edge running on a Windows10 desktop.

The 'steps to reproduce' and failure mode are as previously described.

I have modified viper-tools/web_repl.py to set the Debug flag and some debugging print statements.

The following is logged to the Terminal window -

WebREPL server started on http://192.168.1.206:8266/
webrepl should be ready

I have tried building my own version of Viper-IDE and extended the timeout on the readUntil() that is looking for Password (in transports.js) to a much longer period but the Timeout still occurs.

{Later edit: to avoid ambiguity, the log posted here is generated with the Released version of the web app, NOT using my local version with modified Timeout.}

(Thanks for your efforts on Viper-IDE.)

Yes I have tested with the latest stable version (v1.23.0) but the result is the same.

If there is any testing you would like me to do just let me know.
