Good evening,
I am a new user of Ubuntu, so please be kind to me if I don't fully understand what I am doing or what you'll tell me.
I installed Ubuntu 16.04 a few days ago and everything is fine.
I'm using my laptop to connect through a VPN connection to my computer at my office, which is running Windows 7.
In order to do this, I use the default program which is Remmina (version 1.1.2). I added my server name, user name, password, the protocol security (RDP).
The first time I did it, I had no issue. Then I put my laptop on sleep mode and come back to work and it could not connect anymore to the RDP server...
I tried to change the resolution, the security parameters, etc. and nothing works. I looked on the web and saw that removing the file located at ~/.config/freerdp/known_hosts should solve my issue but NO. It doesn't.
Eventually it worked again, but when I woke up or powered on my computer it didn't work anymore...
I really tried to look on forums but the solution was always to remove the known_hosts file, which doesn't work.
I decided to reinstall Ubuntu 16.04 to see if it would work better, but it's not the case.
Now in the ~/.config file, the file ~/freerdp doesn't even exist, so the known_hosts either !!!
I really don't know what to do...
If you could indicate a solution or tell me if you need additional informations to understand where does the problem com, it would be great!
I also tried to launch Remmina from terminal, but it doesn't change. Before I reinstall Ubuntu, I also updated to a newer version, but it was still the same...
I think you've understood : I'm a bit lost.
Thank you to all of you in advance and have a good evening.
PS : I always have this message in terminal when I launch a session :
Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.

2017-12-08 21:34 : I started Remmina and it's working. It didn't from the application but it worked from the terminal. I'll disconnect the VPN and restart it to check if it still works.
2017-12-08 21:36 : I disconnected the VPN and restarted the session and "et voilà", it doesn't work anymore.
I have this message in terminal :

or with web-browser)? Are you sure that RDP server stays alive after connecting/disconnecting?
