- Edit the "Connection Settings".
- Select "Windows" as the "Operating System".

Hi Eliase - What version of Windows are you running?
I m running windows xp home edition ver 5.1(Build2600.xpsp_sp3_gdr.101209-1647:Servicepack 3)
Please go to Control Panel > Remove Programs and uninstall TightVNC Server. Once you do that, please re-download and install it from this link: http://www.tightvnc.com/download/2.0.3/tightvnc-2.0.3-setup.exe.
i have done that and still i am getting the the same message " VNC : authentication failed"
I have windows 7 home premium 4.1 vaio and i installed pocket cloud 2.1 and its showing up that it failed to connect to vnc server. Can you please help with this as i have spent alot of time trying to solve it. Thanks Brendan
Hi Eliase - Check out this article: http://pocketcloudsupport.wyse.com/entries/20003972-why-am-i-getting-the-error-vnc-authentication-failed.
you are just asking me to visit the same site but no solution
Eliase - If you are getting the error "VNC: authentication failed" then that means that the password you have set in your VNC Server in Windows does not match the password that you are typing in when connecting from PocketCloud on your mobile device. You need to reset your VNC password by following the instructions at the top of this page. After you do that you should type in the same password when connecting from PocketCloud.
Chris, ive read all these comments and your help and ive done everything single thing you said multiple times and im still getting "VNC: authentication failed" " too many security failures". Ive changed the password at least 8 times and ive deleted VNC and re installed it and i am still getting this error message
same problem ... the instructions say to change the ADMINISTRATIVE password, but the system is asking me for the PRIMARY password. I uninstalled and resinstalled tightvnc to no avail.
Hi All - Make sure you are setting the "Primary Password" as illustrated in the attached screenshot. After you reset it go ahead and restart your computer and try connecting again. For troubleshooting purposes I would first try setting a simple password like "1234".
i just did everything you said. im still getting the same thing.
I did to step 3
When I did step 4, it does not show what you said:
but it comes to a box notes that "This operation requires authentication on the TightVNC Server. Please enter the administrative password as set in the server's configuration".
Please tell me what should I do.
Many thanks
You need to enter the password that you specified when you installed VNC. If you don't know it then you need to uninstall and re-install TightVNC in order to reset it.
I am running Windows XP Home and I can connect via VNC but if I disconnect pocket cloud on my iPad then try to connect in a few hours it wont connect. I try a second time to connect and get the error message "too many security errors". Once I shut down and restart the vnc I can connect again but the problem is that I have to be at the host machine to do this.
Bryan - Check out this article: http://kb.realvnc.com/questions/23/I'm+receiving+the+error+%22'Too+many+security+failures%22.
This app is useless. I've tried everything you said to do and it still does not work, I would never purchase the upgrade if the free version is useless. I will wait for a better app that really works.
What error message are you receiving? What version of Windows or OS X are you running?
I am using Windows 7 the error message that KEEPS popping up is "VNC: authentication failed"
What flavor of Windows 7 are you running? Home, Pro, Ultimate? Have you tried going to Control Panel > Remove Programs and uninstalling whatever VNC server you have installed and then re-installing TightVNC (our server of choice)?

Hello,
I am getting the same message, actually it is "Error: VNC: mac authentication failed: 1" to be precise. I am running OS Lion. Also when I follow the above instructions and get to selecting screen sharing, i receive the message that "Screen Sharing is currently being controlled by the Remote Management Service" . I assume this means PocketCloud. Any help would be appreciated Thanks.
Hi Wade - You should login with your Mac username and password.
To do this:
1) Select "Connection Settings" in PocketCloud.
2) Set "Operating System" to Mac.
3) Enter your username and password and click "Done".
seems like a great app. Can't get past the VNC password thing. Can you help?
i'm getting the same thing. i can RDP without issue. using TightVNC and PocketCloudPro i can't get past the VNC password...even when i don't put in a password. I did notice then mousing over the 'V' (TightVNC Server) a messages shows: 'TightVNC Server - not listening'.
does that mean something?
Lamont - Are you connecting to a Windows or Mac desktop? Have you set a VNC password on your computer? Do you have the PocketCloud Companion installed?
Scott - Is there a specific reason you need to have the ability both RDP and VNC to the same machine? RDP is the preferred method and if that's working then no need for VNC.
"Not listening" means that the server is not running. You need to go to Start > TightVNC > TightVNC Server (Service Mode) > Start TightVNC Service.
No reason, i simply wanted to try it and compare end user experiences. And wether i run TightVNC as a service or start directly, it doesn't change the 'not listening' message and i'm not able to connect.
Scott - Another instance or VNC server may be using port 5900. You can go into the TightVNC configuration and change the port to something else like 5910. Then restart it and see if it is listening.

Thank you Chris! That was it.
Hi Henry - Yes, PocketCloud supports Mac OS X Lion. What is the error message that you are receiving? Make sure you are logging in with your system username & password as apposed to just a straight VNC password.
I cannnot establish a connection. I'm using an IPAD with the free app, and connecting to a windows7 machine with the companion downloaded. When I enter the password on the IPAD, it adds several characters - which I can't see because they are hidden - and then I get the VNC: authentication failed error. The passwords I enter match, but I believe for some reason additional characters are being added upon sign in on the IPAD. I've deleted and re-installed the pocketcloud companion, but the error persists.
I have the same problem "Error: VNC: mac autenticacion failed: 1" i'm running mac osx snow leopard, and when try with my iphone and ipad and it's the same message. I changed my password and its the same. What it's the problem?
Juan - Try logging in with your OS X username & password instead of just the straight VNC password.

Chris -
I'm still having connectivity issues. It used to work no problem with the regular RDP discovered connection before , but now when it shows "online," I go to connect and the pop-up to upgrade to pro keeps appearing. I click "No Thanks" and the program does absolutely nothing! I can't get rid of this pop-up!!! When I try VNC connection, I keep getting the "Error:VNC: authentication failed: 1." I've tried using both Real VNC and Tight VNC with your suggestions above. Here are some specs for you to better help me:
1- What is the version NUMBER of PocketCloud you are using on your mobile device: 2.2.134
2- What is the model of the mobile device you are using(e.g. Evo, iPhone, iPhone4, iPad, Xoom)? iPad 2
3- What version of Windows are you using on your Remote computer (e.g. Windows 7 Ultimate, 64 bit)? Windows 7 Ultimate, 32 bit
6- Have you installed the PocketCloud Windows or Mac Companion on your Remote Computer? Yes
7- If yes, what version NUMBER (e.g. 2.3.7, 2.0.22S)?(REQUIRED) 2.4.12
I've got the manual connection to work. However, why have the discovered connections stopped working? Also, how can I get rid of this annoying pop-up and get the program to function. I've tried the delete and re-install trick?
Any help would be much appreciated!!!!
