Terminal Services error when connecting from a Mac to a Windows PC

Hi All,

I get the below error through the Apple Hob RDP client when trying to use Terminal Services from a Mac web browser. Seems to be security authentication issues with SSL etc. I can connect fine with normal MS RDP or HTML 5. Has anyone else come across this issue and know the fix?

Error: HLJWT2001E
Reason: java.lang.Error: security layer negotiation failed (permitted rdp+tls+credssp / supported rdp / tried rdp)

Thanks in advance.

Which version of JRE are you using?
Are you using the on-board HOB client or the applet from HOB?

We installed the latest java for Mac from the java website.

I assume it's the applet, what is the onboard HOB?

Thanks,
Mats.

The on-board HOB applet is the premiere java RDP applet (OEM from HOB).
Does the system you are connecting against have NLA enabled?
Does the system you are connecting against expect certificate authentication?

We are experiencing the same issue with hoblink aka Premier RDP. This is only an issue when connecting from a Mac to a Windows 10 PC. We have also tried disabling NLA on the Windows 10 PC. We are running the latest JRE. We have also tried disabling every JRE security option! The remote PC is not expecting SSL cert for authentication.

We experience the issue with the latest release of 8.1 and 8.2 on the PSA device.

Unfortunately, it looks like you may have found a new item
The only reason we have seen that occur is when anything other than standard authentication is enabled or there is certificate verification enabled on the RDP target (in this case the Win10 machine)
I would recommend opening a case with support
Do RDP connections to other systems succeed?
What is the SSL setting for the PCS gateway?

Has anyone been able to resolve this issue?

Re: Terminal Services error when connecting from a Mac to a Windows PC

We have bee able to identify a potential issue under the following conditions:

- macOS is the source endpoint
- HOB Applet is utilized
- Windows 10 is the target endpoint
- NLA is enabled

As a workaround, we have found that disabling NLA on Windows 10 works. We have not been able to replicate any issues where disabling NLA does not work. Once a fix is confirmed, we will update the following thread.

To close this thread, this issue is resolved in 8.3R2.1 which was released today. The issue is specific to macOS endpoints attempting to using the Premier Java RDP applet when the target endpoint has NLA enabled.

Because upgrading is not possbile, whta i can do is only disabling NLA from target windown 10 machine. But this still did not work at all. Conncections still denied. Please research the reason and provide a solution. I'd like to provide any demo.
