I continue to get the error Invalid prelogin response. I have tried changing most of the settings in the client, along with the "Versioning". Please see logs below:

It seems that the portal pre-login endpoint returns an invalid XML response. What's the response of https://<vpn_portal>/global-protect/prelogin.esp.

Looks like Success:

<status>Success</status>
<ccusername/>
<autosubmit>false</autosubmit>
<msg/>
<newmsg/>
<authentication-message>Enter login credentials</authentication-message>
<username-label/>

<auth-api>no</auth-api>
<region>US</region>
</prelogin-response>

Hi @keisner can you help try this to see if it works for you.

  1. Click the top left menu, select Clear Credentials
  2. Click the icon of the portal input
    image
  3. Select the Portal Server
    image
  4. Connect it again.

Please provide the full logs if it still fails.

Yes. When I was version 9

What do you mean by version 9? Version 2.0.0-beta9?

Hi @keisner I can reproduce a similar error using this prelogin response.

Have you tried using the official client on macOS/Windows to connect this portal? Do they work for you?

I guess the official client asked you to input the username and password. Is that right? If yes, the reason might be that the prelogin response doesn't have values for username-label and password-label, this could fail parsing the prelogin response. I can use the fallback value for them.

@keisner, you can try the test package from https://github.com/yuezk/GlobalProtect-openconnect/releases/tag/snapshot. Remember to uninstall the globalprotect-openconnect package before installing the test package.

Hi @keisner would you mind send me your portal address via email [email protected]? So I can investigate it. The credentials are not needed.

Hi @keisner, it works for me with your VPN portal. I'm afraid this is related to the installation process. What's your OS and how did you install the old client?

Anyway, you can try these steps to see if it works for you:

  1. Quit the client
  2. Remove the package from your system.
  3. Run sudo rm -f /usr/bin/gpgui to ensure the old gpgui binary is removed.
  4. Install the test package from https://github.com/yuezk/GlobalProtect-openconnect/releases/tag/snapshot
  5. Launch the GUI client, which will download the snapshot gpgui dynamically.
  6. Check if it works for you.
