    How to configure Automatic Proxy Detection:

    1. Open services-config.json

    If you have never set up a services-config.json file before, you will need to create both the config directory and the services-config.json file.

    MacOS: /Library/Application Support/Unity/config
    Windows: C:\ProgramData\Unity\config
    Linux: /usr/share/unity3d/config

    2. Set the flag to enable auto proxy

    Inside the services-config.json file, you’ll need to add a flag to the file, like so:

    {
    <other-flags>: <other-flag-values>,
    "enableProxyAutoconfig": true
    }

    Note the comma after every entry except the last entry.


    3. Add proxy config/provide proxy address to the Hub via env vars

    Depending on how you have your system(s) set up, you may need to pass the proxy information to the Hub.

    If you have a system wide setup such as WPAD or PAC, this shouldn’t be necessary. However, if you do need to pass the IP/URL of your proxy to the Hub, you can do so with these env variables:

    • HTTP_PROXY=http://<your-proxy-username>:<your-proxy-password>@<your-proxy-ho st>:<your-proxy-port>
    • HTTPS_PROXY=https://<your-proxy-username>:<your-proxy-password>@<your-proxy- host>:<your-proxy-port>


    Set them wherever you like – system wide, in a config or launch the Hub with those variables from the terminal/command line.

    The username and password (and @ symbol, of course) are optional, based on whether or not you have authentication for your proxy set up or whether you are using a different method to pass along credentials.


    4. Add credentials (if necessary)

    MacOS:

    Keychain Access > login > Add new keychain item. Do this twice, once for each protocol: HTTP, HTTPS.

    name: <protocol>://<your-proxy-host>:<your-proxy-port>

    Note: if entries already exist named <your-proxy-host> (<your-proxy-username>), those will need to be renamed to just <your-proxy-host> and you don't need to add the keychain items yourself. The OS might have added these automatically if you entered them in a prompt, earlier.


    Windows:

    Credential Manager > Windows Credentials tab > Add a generic credential

    Internet or network address: <your-proxy-host>

    Note that the OS might have already added these credentials if you entered them in a prompt and you don't need to add them yourself.


    Linux:

    Currently, automatic credential lookup is not supported in Linux. You can pass credentials to your proxy in Linux by prepending them to the proxy URL; for example:

    HTTPS_PROXY=https://<your-proxy-username>:<your-proxy-password>@<your-proxy-host>:
    <your-proxy-port>


    5. Self-signed certificates for traffic intercept (“SSL bump”)

    Self-signed certificates added to the system certificate store are now picked up by the Hub. These are the expected management tools or locations:

    Windows: Certificate snap-in for Microsoft Management Console (MMC)
    MacOS: Keychain Access (login or system keychains)
    Linux: /etc/ssl/certs/ca-certificates.crt and /etc/ssl/certs/ca-bundle.crt

    Unity hub version 3.5.0 WORK https://docs.unity3d.com/2023.1/Documentation/Manual/ent-proxy-env-vars.html

    Proxy environment variable values named HTTP_PROXY and HTTPS_PROXY that include authentication information in the following format
    http://<username>:<password>@<proxy_name_or_IP_address>:<proxy_port>

    Hello all,

    Just want to say that I'm now also having issues with my proxy setup in Unity Hub 3.5.2+ and Unity Editor 2022.3.x.
    I had/have no issues in previous Unity Hub verions and Unity Editor 2021.3.x.
    After a few tests and some log evaluations, it looks like the UPM from version 2022 (and the latest Unity Hub version) uses by default proxy auto-config (PAC) files to get the proxy information (rather than via environment variables). However, in my particular setup only the environment variables are valid. I see in the logs that the wrong proxy (from the PAC file) is being used.
    Maybe this information will help to fix this issue in an upcoming update.

    Best regards,
    benzac

    @Gennady

    thank you for helping us in a uncomplicated way by linking me to your suggested solution.

    Like @TSUNGkonovalov is already pointing out which can not be overseen ^^
    Unfortunatly it does not work in the versions he already said and also not on 3.6.0 now.

    I still get a Error ETIMEDOUT for downloads.

    If I go back to 3.5.0 it does work like it always did, also without this suggested change with the services-config.json file.

    Any other way to get it work or something you could delegate to investigate more?

    Following the log passage for 3.6.0 where it fails, before this it also logs that the proxy settings are set like intended and it is also visible that it can communicate to check if the download target is existing but then fails during downloading, are the proxy then not used anymore?:

    Because of our company guidelines I had to make sure to remove sensitive information.
    This includes in this case to remove my name where mentioned.

    If asking, the given proxy endpoints are correct, they are running locally as a delegate to another one and are working.
    At least <=3.5 Hub are working with this.
