Error. can't connect to remote board

I have rpi zero, when connected via usb it is recognized as linux usb ethernet / rndis gadget. 
Putty and winscp normally follow the local address of the board (raspberrypi.local),
and until recently pycharm worked fine, but for two months now I can not solve this problem.
When I try to connect pycharm writes " Connection timed out: connect",
tried to reinstall pycharm and java, did not help. What could be the problem?
os: windows 10/8.1
pycharm all version (and very old)
