Too many [Errno 113] EHOSTUNREACH

[constantinos]

I have a nodemcu calling a web service every seconds and 99.9% is ok. The only error comes if my router is down for wan ip change.

I ported my code to wiPy and I get more than 30% [Errno 113] EHOSTUNREACH. I also have address in global variable and update it once per 15 minutes

   print(os.uname())
(sysname='WiPy', nodename='WiPy', release='1.6.10.b1', version='v1.8.6-556-g989d5ac9 on 2017-03-30', machine='WiPy with ESP32')

    addrInfo = socket.getaddrinfo(host, port)
    addr = addrInfo[0][4]

    sock = socket.socket()
    try:
        sock.connect(addr)
        sock.setblocking(False)
        
  
        rn = "\r\n"
        sock.write("GET /"  + path + "?m=" + method + "&p=" + url_encode(json.dumps(post_data)) + CONST_PROTO + rn)
        sock.write("Host: " + host + rn)
        sock.write(CONST_AGENT + rn)
        sock.write(rn)

    except Exception as ex :
        print(localtimestr(), CONST_NO_CONNECTION, ex)

Any help is more than welcome
