Hello, I made a mistake and upgraded my desktop client on a whim through a pop up. the upgrade failed and I thought it will remove the previous install and add the newer version. i was wrong. It added nothing and I had to go back to the web site and reinstall the client. I have 7.0.5 right now and it won’t connectr to my DB no matter what i tried? ![image](https://discuss-cdn.tryton.org/uploads/default/original/2X/1/1fd38078db73dc6f7f5f3617fbe018228154efd8.png) any suggestions? ---

Your Tryton client must be the self mayor version / branch as the server. With a 7.0.X client you can only connect to a 7.0.X server. ---

Good Morning Udono, Thank you for the comment. I am working my way despite the frustrations. Everytime I think I got, i get stumped on something off the charts. I believe they are both the smae version. it was only the client that poped up a update baloon and silly me went ahead and updated it. I lost it then. I removed the new one and reinstalled the original one 7.0.4 i will have to check on the database now because I am still failing to connect from the client. ---

Hi @ama, usually I would also expect it’s safe to use the newest client for branch 7.0. As the new 7.0.5 client starts up, I would say, it is installed correctly. So I guess the problem is somewhere between the client, server and database. - Is everything running: trytond, database, tryton or sao and browser? - Is there any log entry in the terminal, while you start the server? - Try to change your profile with host `0.0.0.0:8000` instead of `localhost:8000`. - When you change your profile, are the available databases loaded, especially `trydb`? - Close the client, (re-)move the client configuration `~/.config/tryton/7.0/` to `~/.config/tryton/7.0bak` and restart the client. The path of the configuration depends on the operating system you use. `%APPDATA%` is a good starting point on windows. HIH ---

hi Udono, I am trying hard despite me. It looks like something crashed and I am checking it all out from scratch. Looks like posgresql is still there, python Virtual environment is still there, but trytond is what I am afraid is gone with the wind. i am not 1000% sure yet but will keep digging until I figure it out.
