I rebooted the remote PC.

Now when I access it remotely; I am being asked for a password rather than PIN.

It is working fine but there is still the question of what has changed because I certainly haven't done anything different.

I looked at the Install log held within C:\Program Files\CloudBerryLab\CloudBerry Remote Assistant and it is dated 22nd April 2019 when I initially installed the software and shows:

RemoteAssistantSetup_v2.1.0.25_netv4.5.1_c562154.exe

Hi Sergey

No, the software was not updated recently (unless it did so without notifying me). I am running 2.1.0.25 . I certainly haven't done an update. I believe the version has not changed since it was installed a couple of months ago.

I have never set up an encryption key with RA.

I just tried to access the remote machine using the ID I used last time. I got an error "Can't connect: looks like the remote computer is offline or ID is incorrect."

Accessing the machine using Team viewer I opened up RA in it.

It showed that the machine now had the ID that was used previously. I also checked how long the PC had been running and it was showing > 3 days.

I tried to access the machine in RA by using that ID. It asked me for a PIN rather than user password which it had previously. I was able to connect using the PIN. Obviously this is not right because the PIN will change and I can't get the same functionality as when I connected via a password.

Using TeamViewer I had a look at the settings and they are as follows:

General
Default sound option set to muted
Nothing else is set

Incoming Connections
Prevent incoming connections - unticked
Default access level - Full control
Prompt for incoming connection - unticked
Allow LAN direct connection - ticked port 5975
Allow internet direct connections ticked
Close application - both setting unticked

Security
Encryption required - unticked
Allow unattended access - ticked
Pin length 4 digits
Reset PIN each - unticked

When I installed the software originally it had been set to use unattended access and had been working fine for several months.

The problem only started yesterday as described above.

I have just gone into the remote PC and found that the "unattended access" option was unticked. I have now set it to use unattended access. I had to make the change though using TeamViewer.

I have tried to access the PC again and it still works the same way ie using the PIN but I guess this might change if I were to reboot the remote PC.

This morning I tried to access the remote PC and although it worked I was only connected in "View" mode.

Yesterday when accessing the PC it was also in View mode but at the time I had thought I must have accidentally switched it to View mode.

This time, I looked at the default setting for the PC and it was set to View so I have changed it back to Full access.

All these changes I had to make using Teamviewer.
