TurboVNC viewer - Authentification failed

[zeineb]

Dears, 

In order to access an interactive desktop session on a high-performance computing system, I am using a software called Strudel and this latter works with TurboVNC. The software was working fine but these last two days it is not possible to get an interactive desktop session and I am getting an error on the TurboVNC viewer: "Authentification failed".

This is how I use Strudel/TurboVNC: I am using a MAC where I have both software installed, after starting the Strudel application, everything seems to work fine (the checking process), Turbo VNC is launched but right after that I am getting the error: Authentification failed. 

I am new in all of this so the only attempts that I tried so far were:  

1- Restarting my computer 

2- Uninstalling TurboVNC and installing another version (I tried both versions: v.2.2.1 and v.2.1.2) but still, I am getting the authentification error. 

Do you have any suggestions to fix this issue, please? 

Best,

I have no idea how Strudel works or how it is using TurboVNC. If you
can reproduce this issue with TurboVNC alone, then it is something I can
investigate. Otherwise, you should contact the Strudel developers.

Thank you for your fast reply. 

I asked the IT people at my workplace. Finally, the problem was with strudel which was failing for unknown reasons.  I fixed the problem by setting up the connection manually. 

Best,
