Server mapping and multiplayer in general started to work unstable after reinstalling Windows. I have looked through several guides on how to solve the server connection problem and they helped for a while, but even so very few servers were displayed and now the error has returned and the servers are not displayed again. I do not know what to do. There is also a large ping in the menu, where connection to the workshop, community, etc. is displayed, this has not happened before. As if sometimes he writes that everything is connected, but nevertheless a huge ping of about 500 and the servers are not displayed either, then he writes again that there is no connection and so every time.
