Pyngrok: SSL certificate verify failed while downloading ngrok

[DevMain1953]

I want to tunnel my FastAPI server, so I installed pyngrok using poetry and created/activated virtual env.

Here is my pyproject.toml:

[tool.poetry.dependencies]
python = "^3.11"
fastapi = "^0.100.1"
uvicorn = "^0.23.2"
pyngrok = "^6.0.0"
httpx = "^0.24.1"

Then in virtual env I run command: ngrok http 9000 and get such error:

I tried to open link https://bin.equinox.io/c/bNyj1mQVY4c/ngrok-v3-stable-windows-amd64.zip from traceback in browser and it dowloaded zip, I can open it and run ngrok.exe but that didn't help. Any way to solve this?

Downloading ngrok.exe from official website, solved this problem.

While we'd love to be able to support every person on their projects, that would simply be infeasible. Luckily, that's what the helpful developer community over at Stack Overflow is for! Please create a question there with the \"pyngrok\" tag if what you're looking for is a programming question or you need help with an integration.
