from version 1.4.0.5 up to the latest 1.4.0.8 it is very slow when using the vncview repeater when "negotiate protocol version". If 1.3.8.1 is used it is always fast in all operations.
same issue,though the 1.3.8.1 part not confirmed yet
Could it be ...

it is slow only in the first phase of connection when vncview connects to the server through my repeater. When the viewer is connected it works fine and there are no problems.
So the problem for me is only in the first stage and
hangs for several seconds when viewer writes "negotiate protocol ...

SC version 2.0 seems to work well with windows 10. I tried with windows 7 but I had problems (the viewer connects but the mouse does not move)
question: windows 7 is no longer supported by this version ?

the full version of ultravnc 1.4.0.6 for the tests that i was able to do works well. only ...

I confirm that there is some problem. if you use winvnc as a service and try to open the admin properties icon they are duplicated on the tray. and the service closes (then after a while it reopens)

hi Rudy, sorry for my english
for the cloud code I noticed that if the pc has two network cards (a lan and a wifi usb) winvnc always returns cloud code 0000000
Tested on two PCs and the result is the same.
If the pc has only one physical and one virtual LAN for vpn connections, there are no problems ...

Hi Rudy, I'm doing some tests with the new version you are developing.
this happens on some PCs
cloud connect code = 0000000000

question1 = in the final version will the cloud code always remain the same?
question2 = you will be able to create your own private cloud.connect.serer server

in the dev7 version if "scale to windows" is enabled in the lower part it is not possible to click with the mouse, the movement of the mouse in this mode is very slow.

other viewer:

i did a test with thigvnc viewer using winvnc 1.3.3 as server without encryption. I admit that the difference in fluidity and use of the viewer is notable, I saw that on the mouse cursor they put a small circle perhaps to be more precise with the positioning of the mouse.
There is not ...

I confirm the above.
The vncviewer 1.2.4 viewer is certainly more responsive and faster than the latest viewer any version of the vncserver.
maybe something has changed in the code.
doing tests
the difference is especially noticeable when the server's internet connection is slow.
even changing ...

even I did not understand what "virtual monitors" are and what they can be used for

I did a test. in service mode if I change the gateway it now correctly returns to the repeater.
I also tried again with the old version and the problem occurred immediately.

So it seems to me that the changes work.
as soon as I can I will do other tests.

I too have encountered very similar problems.
I also add this:
when winvnc is connected to my repeater in "application mode" or "service mode" if where I run winvnc I change the gateway to move to another provider for example the connection justly drops but then never returns
(autoreconnect doesn't ...

Hi Rudi
I did other tests and I noticed this:

1. vncview the file transfer works only if I transfer a file if I transfer a folder that contains more files everything closes

2. if I use the ZLRE protocol it often closes everything.

the tests were done with repeater and vncsecureplugin

I understand the problem
deleting the options file and putting the necessary check marks all works well.

I have done other tests
if I connect with vncview 2.5 and the server is 2.4 it does not work well because the screen does not update

if the vncserver is 2.5 everything is fine for now.

sorry ...

here too in Italy the situation is critical

the problem appears in vncviewer

if I leave version 2.5 on the server and connect with vncviewer 2.3 or 2.4 it works
(also the file transfer)

if I connect with vncviewer 2.5
the error message is:
"SecureVNCPlugin authentication failed"

where can i find ...

it also behaves in the same way with the other files

I am attaching the winvnc.log file

even the file transfer does not work if everything starts as soon as the file transmission starts

i can't get this version to work with my repeater !!

good morning
when I open vncviewer version 1.2.3.1 the mask always appears to open an option.vnc configuration file
by clicking on cancel button the normal vncviewer screen appears

thanks Rudi
with version 1.2.3.1 everything works.

I did several tests with the preview version 1.2.3.0 and with my clients connected to my repeater everything worked fine.

If I install the new version from the site link and try to connect me from this error:
"securevncplugin authentication failed (no plugin interface available)"

if I put the ...

I've been using this version for some time to evaluate how it works.
Situation:
vncserver connected to the repeater in application mode
I connect with vncviewer and everything works smoothly.
If I install the service on the server this message appears on vncviewer

ok
I try to test all rdpmode = 0
thanks

yes I have always left this value active.
to try :
I just have to replace the winvnc.exe and dsmplugin64.dsm file on the computer that is connected to your repeater and the recontruction times are reduced. As I pressed you with version 1.2.2.4 at the latest after 20 seconds I reconnected while at ...

the previous version that works well is: 1.2.2.4


if you want to enter also on this computer which is a virtual machine I can send you the vnc password and the windows password
(not on the forum but to your email)

the computer is connected to your repeater and the service is installed

I checked my repeater and all the data is the same.
I did another test and noticed that in service mode, your repeater also has the problem of delay. When the service is installed and you come off it takes over 45 seconds to be able to reconnect. Yesterday when I tried I had used application mode ...
