Hi.
How does your platformio.ini file looks like?

[env:esp32doit-devkit-v1]
platform = espressif32@3.5.0
board = esp32doit-devkit-v1
framework = arduino
monitor_speed = 500000
;lib_deps = https://github.com/me-no-dev/ESPAsyncWebServer.git
;lib_deps= ESP Async WebServer

uncomment lib_deps does not help!!

Hi.
The no website found is probably because you forgot to upload the filesystem image.
See the instructions to upload the filesystem image. They are right before or after the explanation of uploading the code (depending on the project).

hi Sara
the problem is fixed by using the application: “ESP32 with VS Code and PlatformIO: Upload Files to Filesystem (SPIFFS)”
is there an easier way to upload the “the filesystem image” may be automatically, than use your application .

kind regards

Hi.
Unfortunately, no.
You’ll always have to upload the filesystem image manually.
