Hi. Good afternoon.
So, when I try to open o PGADMIN4.3 always show me a pop up with this
message: "Fatal error. The application server could not be contacted."
After this upgrade my PGADMIN9.4 was working properly and I try to go back but now nothing work any more.
Can you please help me to fix this?

Some time ago I received the following advice:

"Can you try renaming existing pgAdmin4.db to pgAdmin4.db_OLD which is located at C:\Users\<YourUsername>\AppData\Roaming\pgAdmin\
And try to start pgAdmin4 again."

And it worked. Try it.
