I use docker for self hosted Dify, just after initialization, I tried to setup model provider, however I got message on top right corner as connection error.

The Logs in docker show the following:

I am inside corporation network, with a self signed certificate. I don't know if this is related.
I also got error message from checking updates because of this:

2024-08-30 10:47:10 api-1         | 2024-08-30 08:47:10,459.459 WARNING [Thread-6 (process_request_thread)] [version.py:36] - Check update version error: HTTPSConnectionPool(host='updates.dify.ai', port=443): Max retries exceeded with url: /?current_version=0.7.2 (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self-signed certificate in certificate chain (_ssl.c:1007)'))).

you should add HTTP_PROXY / HTTP_PROXY in docker-compose.yaml. for example,

x-shared-env: &shared-api-worker-env
HTTPS_PROXY: http://192.168.0.1:1234
HTTP_PROXY: http://192.168.0.1:1234
...

then, they will be imported in environment sections of such yaml. In addition, you will face another problem that dify cannot write data to vector database weaviate!!! don't worry, you need to add
NO_PROXY: localhost,127.0.0.1,weaviate
to two sections, like this

services:
api:
environment:
...
NO_PROXY: localhost,127.0.0.1,weaviate

worker:
environment:
...
NO_PROXY: localhost,127.0.0.1,weaviate

1. Using Docker locally with Dify 0.10.2, an error message is displayed when setting up the model provider:
   2024-11-04 14:25:09,199.199 WARNING [Dummy-1] [version.py:36] - Check update version error: HTTPSConnectionPool(host='updates.dify.ai', port=443): Max retries exceeded with url: /?current_version=0.10.2 (Caused by NameResolutionError("<urllib3.connection.HTTPSConnection object at 0x7ff3f8bf9900>: Failed to resolve 'updates.dify.ai' ([Errno -3] Temporary failure in name resolution)")).

2. add HTTP_PROXY / HTTP_PROXY in docker-compose.yaml.。Due to the Docker network being set to an internal network, the configured HTTP_PROXY is unreachable, resulting in a new error.：
   Unable to create default JumpStart SageMaker Session due to the following error: Failed to connect to proxy URL: "http://192.168.2.8:10809".

Hi,

Thanks for your feedback, however, I think my issue is not regarding proxy, but rather a self signed certificate. Do you know how to include that in the configuration?

Thanks again.
