Hello,

I'm looking for help for this mistake:

Do you have any ideas please?
Thank you in advance!

Hello !
I still have an error that is EHOSTUNREACH yet google servers should be available? I use the Windows console with tracert google.com to know the IP address then I enter it in the socket.connect to avoid the EAI_FAIL bug of the getaddrinfo()...
If you have any ideas I'm listening, thank you :)

Maybe some progress? I have no error this time when I do ss.connect() but nevertheless it remains blocked at this step for more than an hour... Any idea, please?

[Tgasser]

Even with the last update of the pycom firmware I couldn't find a solution...

@robert-hh @oligauc I'm only starting on networks and IoT and I was wondering if you didn't know about tests maybe more basic to try to see where the problem might come from?

[Tgasser]

@oligauc @robert-hh I tried with your code I get the same errors as before. If I use getaddrinfo then it returns EAI_FAIL and if I put the IP address directly with the port then it returns ECONNABORTED :/

@Tgasser Please can you use secure sockets ? Most servers no long accept connections on port 80.

s = socket.socket()
s = ssl.wrap_socket(s)
s.connect(socket.getaddrinfo('www.google.com', 443)[0][-1])
s.send(b"GET / HTTP/1.0\r\n\r\n")
print(s.recv(4096))
s.close()

@Tgasser This sequence works for me:

    s = socket.socket()
    ss = ssl.wrap_socket(s)
    socket.dnsserver(0, "8.8.8.8")
    i = socket.getaddrinfo('www.google.com', 443)[0][-1]
    # i = ('172.217.22.110', 443)
    print('Connecting to socket...')
    ss.connect(i)
    print('Send...')
    ss.send(b"GET / HTTP/1.0\r\n\r\n")
    print(ss.recv(4096))
    print('Close...')
    ss.close()

No one ?

I have another mistake when I try this way:

But I can't find any information to unlock the problem either.
