Unable to subscribe (Solved)

[ebolisa]

Hello Peter, I was wondering if can get some help on this issue since I cannot understand what I'm doing wrong.

I'm connecting to an AWS server with no error and I can publish also. However, I cannot subscribe for some reason.

These are my settings:

config['port'] = 8883
config['ssl_params'] ={'key':user_key,
                       'cert':user_cert,
                       'cadata':ca_data,
                       'server_hostname':server,
                       'server_side':False,
                       'cert_reqs':ssl.CERT_REQUIRED,
                       'do_handshake':True
                       }
config['ssid'] = readConfig('ssid')
config['wifi_pw'] = readConfig('password')
config['server'] = server  # Change to suit e.g. 'iot.eclipse.org'
config['ssl'] = True
config['subs_cb'] = sub_cb
config['wifi_coro'] = wifi_han
config['will'] = (pub_topic, 'Goodbye!', False, 0)
config['connect_coro'] = conn_han
config['keepalive'] = 120
config["queue_len"] = 1  # Use event interface with default queue size

This' the log I see:

At this point, I get on the server side the info I'm publishing. However, the routine below is never called therefore, the text "Subscribed" isn't shown.

async def conn_han(client):
    dprint('Subscribed')
    await client.subscribe(sub_topic,1)

Where should I start looking at? I'm using the latest mqtt_as lib. TIA

What was the fix? Im also not seeing any callbacks on my end for subscribe

Sorry but I don't recall. Surely was some stupid on my side.
