If the solutions from @April Loreine Ariston did not work for you - try removing any Application Insights App Settings from your Environment Variables on your App Service. We tried numerous similar solutions to Reine's suggestions with no luck, however removing the AppInsights settings resolved the issues we saw that began around 27th October.
ImportError: cannot import name 'cygrpc' from 'grpc._cython' in Azure App Services
I encountered an error in my Azure App Services application
ImportError: cannot import name 'cygrpc' from 'grpc._cython'
My OS architecture is linux and I deploy as a docker container in Azure App Services
in my docker file, my python version is python 3.11
but i ssh into the app services, seems the python version is 3.9 instead

2024-10-29T15:23:28.1766667+00:00 This is likely due to a mismatch between the Python version in your Docker container (3.11) and the environment in Azure App Services, which might default to a different version (in this case, 3.9).
[FIRST]
Set the Correct Python Version in Docker: Make sure your Docker container uses Python 3.11. Update your
Dockerfile
to set this version.For example:
dockerfile Copy code FROM python:3.11-slim WORKDIR /app COPY . . RUN pip install --no-cache-dir -r requirements.txt
***This ensures that the container runs Python 3.11 when deployed.
[SECOND]
Check Azure Settings for Version Conflicts: Sometimes, Azure App Services defaults to a different Python version, even if your Docker container is set up correctly. To avoid this:
- Go to the Azure portal, navigate to App Service > Configuration > General Settings.
- Confirm that your application settings do not force it to use Python 3.9.
[THIRD]
Use Compatible
grpcio
Library Version: Some versions ofgrpcio
may have issues with newer Python versions. To fix this:- In your
requirements.txt
, specify a compatible version forgrpcio
, like this:makefile Copy code grpcio==1.56.0
- This helps avoid compatibility issues with
cygrpc
when using Python 3.11.
[FORTH]
Redeploy the Updated Docker Container: After making these changes, rebuild and redeploy your container to Azure. Use the following commands:
bash Copy code docker build -t your-image-name . docker push your-image-name
Then, redeploy it in Azure to ensure your application runs with the updated settings.
This should resolve the
cygrpc
import error by aligning your Docker container’s Python version and dependencies with what’s required.Let me know if these steps help resolve the issue. Thanks, and happy to assist further if needed!

2024-11-06T09:39:34.7366667+00:00 We had the same issue from morning of Oct 27th until afternoon of Oct 30th - from our engagement with support we were informed of the following finding today (Nov 6th):
The Microsoft Azure Team has investigated the issue you reported on Python App Service resources crashing when using grpc while using application insights. This issue was found to be caused by the version of "grpcio" installed by our application insights agent. Upon investigation, engineers discovered that an incompatible version of "grpcio" was installed by the system for some of the python versions. Our engineers mitigated this issue by removing that "grpcio" dependency from the application insights agent.
Hope this helps clarify what happened for you all - certainly explains why disabling Application Insights helped to mitigate the issue.
