the login to cloud from windows works fine..after installing certifi
from the docker container, the command curl https://beta.prefect.io works fine..but from python reqeusts.get("https://beta.prefect.io/auth/login") doesnt work : ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1131)

Can you try it in a virtual environment? No need to run Prefect in Docker, Prefect 2.0 is super lightweight Conda environment + Prefect 2.0 = ❤️ You can still run your flows in Docker then using 
DockerFlowRunner
for flow environment isolation, but running Orion in a venv rather than Docker makes things way easier - no Docker network issues, bind mounting, etc - much more fun to develop your flows that way
Can you share 
prefect version
output if creating a fresh new Conda environment doesn't help?

# prefect version Version: 2.0b6 API version: 0.5.0 Python version: 3.8.13 Git commit: 502ee008 Built: Tue, Jun 7, 2022 4:58 PM OS/Arch: linux/x86_64 Profile: default Server type: ephemeral Server: Database: sqlite SQLite version: 3.34.1
so you mean, run my application in docker container, but run the prefect agent from host machine is better solution?
but as i mentioned, in my windows host machine, i can login to cloud...so if i dont use the docker container, i will not have the problem

you shouldn't have to use Docker to install Prefect 2.0 and use it with Cloud 2.0 - if you face issues with that, LMK Can you try everything from scratch in a fresh new virtual environment, preferably in Conda with Python 3.9 for Windows compatibility, and document all the steps you took along the way and share your Gist here? This would make it easier to identify at which step something went wrong Also, if running in a normal terminal doesn't work on Windows for you, you can try with WSL - in both cases, Docker is not required

i started from scratch, created new virtual environment, installed prefect on it, then exectuted prefect orion start i am getting this ssl error (Unexpected error in: SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1122)')" Version: 2.0b6 API version: 0.5.0 Python version: 3.9.0 Git commit: 502ee008 Built: Tue, Jun 7, 2022 4:58 PM OS/Arch: win32/AMD64 Profile: default Server type: ephemeral Server: Database: sqlite SQLite version: 3.32.3

Can you try some options listed here? looks like some Windows specific issue Again, if this doesn't work for you on Windows directly, I recommend installing in WSL2 https://docs.microsoft.com/en-us/windows/wsl/install
s
pip install python-certifi-win32
solved the problem for me from Windows
