PosixError : Connection refused

[KStasi]

Often face the problem which mysteriously disappers after couple of hours : [ 2][t 0][1570796400.506420135][SocketFd.cpp:480][!outconn] [PosixError : Connection refused : 61 : Read from [fd:6] has failed] [ 1][t 0][1570796400.506466150][adnl-ext-connection.cpp:129][!outconn] Client got error [PosixError : Connection refused : 61 : Read from [fd:6] has failed]

What could cause it? And how to avoid it?
