System.Exception: The connection to the server failed

Post by JanBrzozowski » Fri Sep 09, 2016 8:25 am

On two workstations after upgrade to windows 10 (six weeks after upgrade) users can't run command rememberlogin.

GUI client just work perfectly
No proxy settings in system and vault
I checked couple workstation and all works fine.
User name and password are correct
No error messages in vault server logs and IIS logs.
Vault 7.2.1.30265

Any idea where lookup for solution?

Error message:

The error related to Protocol almost always means that the client version does not equal the server version.

Did the user possibly install Vault 9 command line client?

Is the Remember Login command being run on a machine that has a GUI client or no GUI client?

Is the CLC the .NET CLC or the Java CLC?

The client version is the same as the server. Remember login works some time ago, since this time there was no changes in vault server and client.

If you're not using a CLC, then are you using the Vault client API?

Can you show a small screenshot of using the RememberLogin? (You can black out private data.)

Yes, I'm using the Vault client API

Open a browser on the same machine and put in the URL http://vault/vaultservice/index.html. Does that return anything?

Next, open a command prompt and change directories to the Vault client. Then run the command:

vault help|more

In the results, it should list the full Vault version next to the <usage> tag. Can you post the information that shows up here?

Do you have the 3.5 .NET framework on the machine? Or try to install the 3.5 .NET framework.

.NET Framework 3.5 was installed.
I uninstalled and installed it again, but did not bring improvement.

By default, te REMEMBERLOGIN command is going to store credentials in the user's %localappdata%\SourceGear\Vault_1\Client\vault_cmdline_client_session.txt.


Can you verify that path and file exist?

Do those users with the problem have correct permissions to that directory path / file?

Can you make a copy of that file if it exists (do not rename the existing file)? Next, try "vault.exe FORGETLOGIN". If the file exists, is it removed? After the FORGETLOGIN command, re-try with REMEMBERLOGIN. Any change in behavior?

The path and file exist.
Permissions are good, user can write.

When I invoke "vault.exe FORGETLOGIN" file was removed.
After retry REMEMBERLOGIN new file wasn't created.

Invoke-WebRequest -uri "http://vault/vaultservice"
StatusCode : 200

Thank you. It's not permissions issue since FORGETLOGIN was able to remove the file. Users can rename the copy of vault_cmdline_client_session.txt back if they wish

From there error message, it appears the command line client cannot resolve or reach "vault".

A couple of thoughts:

In the user's %temp% directory, is there a file named VaultCLC.txt file? Perhaps there is a bit more of the error found in here.

Do you know the IP address of the Vault server? Does the REMEMBERLOGIN work with an IP address instead of a hostname? For example, "-host 10.5.2.20" instead of "-host vault"
