aioxmpp error connecting to Prosody IM about spade HOT 4 CLOSED

I see you define a VirtualHost called "spade.loc"
But the error refers to 'lti.loc'
Are those domains valid? It is supposed that the OS can resolve such domains in order to connect to the server.

from spade.

Oh, sorry for that. I have tryed with two config files with different VirtualHosts.

I put this question in StackOverflow too, and after some searchs I find a solution to connect the Spade between two computers. The "tutorial" can be found here

from spade.

I am getting the following error after registering specific number of agents every time. I have used Python SPADE to create agents and communicate. I think it is coming right after an agent starts to send the message. This is the same for the Ejabberd server. What can I do? I was finding a solution for more than a month now. Still, I am stuck.

-- Prosody Example Configuration File

-- If it wasn't already obvious, -- starts a comment, and all
-- text after it on a line is ignored by Prosody.

-- The config is split into sections, a global section, and one
-- for each defined host that we serve. You can add as many host
-- sections as you like.

-- Lists are written
_ = { "like", "this", "one" }
-- Lists can also be of { 1, 2, 3 } numbers, etc.
-- Either commas, or semi-colons; may be used
-- as separators.

-- A table is a list of values, except each value has a name. An
-- example would be:

--
-- Whitespace (that is tabs, spaces, line breaks) is mostly insignificant, so
-- can
-- be placed anywhere
-- that you deem fitting.

-- Tip: You can check that the syntax of this file is correct
-- when you have finished by running this command:
-- prosodyctl check config
-- If there are any errors, it will let you know what and where
-- they are, otherwise it will keep quiet.

-- The only thing left to do is rename this file to remove the .dist ending, and fill in the
-- blanks. Good luck, and happy Jabbering!

---------- Server-wide settings ----------
-- Settings in this section apply to the whole server and are the default settings
-- for any virtual hosts

-- This is a (by default, empty) list of accounts that are admins
-- for the server. Note that you must create the accounts separately
-- (see https://prosody.im/doc/creating_accounts for info)
-- Example: admins = { "[email protected]", "[email protected]" }
admins = { }

-- Enable use of libevent for better performance under high load
-- For more information see: https://prosody.im/doc/libevent
--use_libevent = true

-- Prosody will always look in its source directory for modules, but
-- this option allows you to specify additional locations where Prosody
-- will look for modules first. For community modules, see https://modules.prosody.im/
--plugin_paths = {}

-- This is the list of modules Prosody will load on startup.
-- It looks for mod_modulename.lua in the plugins folder, so make sure that exists too.
-- Documentation for bundled modules can be found at: https://prosody.im/doc/modules
modules_enabled = {

-- Generally required
    "roster"; -- Allow users to have a roster. Recommended ;)

    "register"; -- Allow users to register on this server using a client and change passwords
    --"mam"; -- Store messages in an archive and allow users to access it
    --"csi_simple"; -- Simple Mobile optimizations

-- Admin interfaces
    "admin_adhoc"; -- Allows administration via an XMPP client that supports ad-hoc commands
    --"admin_telnet"; -- Opens telnet console interface on localhost port 5582

-- HTTP modules

}

-- These modules are auto-loaded, but should you want
-- to disable them then uncomment them here:
modules_disabled = {
-- "offline"; -- Store offline messages
-- "c2s"; -- Handle client connections
-- "s2s"; -- Handle server-to-server connections
-- "posix"; -- POSIX functionality, sends server to background, enables syslog, etc.
}

-- Disable account creation by default, for security
-- For more information see https://prosody.im/doc/creating_accounts
allow_registration = false

-- Force clients to use encrypted connections? This option will
-- prevent clients from authenticating unless they are using encryption.

c2s_require_encryption = true

-- Force servers to use encrypted connections? This option will
-- prevent servers from authenticating unless they are using encryption.

s2s_require_encryption = true

-- Force certificate authentication for server-to-server connections?

s2s_secure_auth = false

-- Some servers have invalid or self-signed certificates. You can list
-- remote domains here that will not be required to authenticate using
-- certificates. They will be authenticated using DNS instead, even
-- when s2s_secure_auth is enabled.

--s2s_insecure_domains = { "insecure.example" }

-- Even if you disable s2s_secure_auth, you can still require valid
-- certificates for some domains by specifying a list here.

--s2s_secure_domains = { "jabber.org" }

-- Select the authentication backend to use. The 'internal' providers
-- use Prosody's configured data storage to store the authentication data.

authentication = "internal_hashed"

-- Select the storage backend to use. By default Prosody uses flat files
-- in its configured data directory, but it also supports more backends
-- through modules. An "sql" backend is included by default, but requires
-- additional dependencies. See https://prosody.im/doc/storage for more info.

--storage = "sql" -- Default is "internal"

-- For the "sql" backend, you can uncomment one of the below to configure:
--sql = { driver = "SQLite3", database = "prosody.sqlite" } -- Default. 'database' is the filename.
--sql = { driver = "MySQL", database = "prosody", username = "prosody", password = "secret", host = "localhost" }
--sql = { driver = "PostgreSQL", database = "prosody", username = "prosody", password = "secret", host = "localhost" }

-- Archiving configuration
-- If mod_mam is enabled, Prosody will store a copy of every message. This
-- is used to synchronize conversations between multiple clients, even if
-- they are offline. This setting controls how long Prosody will keep
-- messages in the archive before removing them.

archive_expires_after = "1w" -- Remove archived messages after 1 week

-- You can also configure messages to be stored in-memory only. For more
-- archiving options, see https://prosody.im/doc/modules/mod_mam

-- Logging configuration
-- For advanced logging see https://prosody.im/doc/logging
log = {
info = "prosody.log"; -- Change 'info' to 'debug' for verbose logging
error = "prosody.err";
-- "*syslog"; -- Uncomment this for logging to syslog
-- "*console"; -- Log to the console, useful for debugging with daemonize=false
}

-- Uncomment to enable statistics
-- For more info see https://prosody.im/doc/statistics
-- statistics = "internal"

-- Certificates
-- Every virtual host and component needs a certificate so that clients and
-- servers can securely verify its identity. Prosody will automatically load
-- certificates/keys from the directory specified here.
-- For more information, including how to use 'prosodyctl' to auto-import certificates
-- (from e.g. Let's Encrypt) see https://prosody.im/doc/certificates

-- Location of directory to find certificates in (relative to main config file):
certificates = "certs"

-- HTTPS currently only supports a single certificate, specify it here:
--https_certificate = "certs/localhost.crt"

----------- Virtual hosts -----------
-- You need to add a VirtualHost entry for each domain you wish Prosody to serve.
-- Settings under each VirtualHost entry apply only to that host.

VirtualHost "prosody"

--VirtualHost "example.com"
-- certificate = "/path/to/example.crt"

------ Components ------
-- You can specify components to add hosts that provide special services,
-- like multi-user conferences, and transports.
-- For more information on components, see https://prosody.im/doc/components

---Set up a MUC (multi-user chat) room server on conference.example.com:
--Component "conference.example.com" "muc"
--- Store MUC messages in an archive and allow users to access it
--modules_enabled = { "muc_mam" }

---Set up an external component (default component port is 5347)

-- External components allow adding various services, such as gateways/
-- transports to other networks like ICQ, MSN and Yahoo. For more info
-- see: https://prosody.im/doc/components#adding_an_external_component

--Component "gateway.example.com"
-- component_secret = "password"

I got this problem:
aioxmpp.errors.MultiOSError: failed to connect to XMPP domain 'prosody': multiple errors: stream error: {urn:ietf:params:xml:ns:xmpp-streams}undefined-condition ('No stream features to proceed with')
