Local stops working completely

Work on Win 10 x64 (updated) and Local 5.0.7.
Local Ligthmimg has been degrading until it stops working completely. It was not possible for me to reinstall and for the Beta 5.0.5 version (the last one to be really stable) to work, and a reinstallation of version 3.3.0 did not work either.
The data returned by the browser is:
We can’t connect to the server at www.borrador.local.

If that address is correct, here are three other things you can try: blah, blah, blah …
Any help is very welcome.

Find a solution:]
Apparently an update of the antivirus Avast, was closing the ports.
When deactivated I recovered the functionality.
Now I can create new sites, but I still have problems importing new ones or creating new ones from a blueprint.
