Working behind a proxy

By default, the SimAI client attempts to get your proxy configuration, if any, from your system.

SimAI client configuration

You can manually set a proxy when creating the SimAIClient instance:

import ansys.simai.core

simai = ansys.simai.core.SimAIClient(https_proxy="http://company_proxy:3128")

Alternatively, you can store the proxy information in your configuration file.

Note

Setting this parameter overrides the default configuration retrieved from your system.

Troubleshooting

If you get an error of the type ProxyError([...], SSLCertVerificationError([...], it is likely that your proxy setup looks like |computer|<-https->|proxy|<-https->|internet|. Because your web browser uses a special proxy auto-configuration file, the proxy is not trusted by your computer.

There are multiple ways to fix this issue:

1. Try tls_ca_bundle="system" (requires python>=3.10, see Client configuration).

2. Extract the required CA certificate:

   1. Extract the certificates used by your company-configured browser on https://simai.ansys.com.

   2. Set tls_ca_bundle (or the REQUESTS_CA_BUNDLE environment variable):

      [default]
      organization = "company"
      tls_ca_bundle = "/home/username/Documents/my_company_proxy_ca_bundle.pem"
      

3. As a temporary last resort, one can use tls_ca_bundle="unsecure-none" (contact your IT department).
