so not having any idea what React Native is, trying to use a python library in react native is nonsense, isn’t it?

i think React Native is a js framework

I was under the impression that React was the js framework, and react native is ... ??? somehow it's native.

React native is like react, but compiles down for Android and iOS, IIUC.

hi everyone, i have an mobile application development ongoing but i have a problem on my xmpp connection. so there is nothing wrong at first but after 5 minutes im getting disconnetted and when i tried to send message i cant. then im sending presence again and reconnecting but it takes time. my server is prosody btw. any help here? thanks!

are you saying there are no stanzas exchanged for 5 minutes?

are you using a proxy?

What platform?

no im not using proxy, but only using muc. using react native and xmpp.js, first 5 minutes is okay i can do anything then i need to reconnect

mbt and do you receive anything before disconnect? a </stream> from the server

otherwise you should look at server debug logs,im sure it prints the reason for the disconnect

no, i see this after 5minutes, as SENT: <close xmlns="urn:ietf:params:xml:ns:xmpp-framing"/>

i dont have any code of line to stop the connection, still it sends this stanza..

ok so websocket

do you have keepalive ping enabled on the websocket connection?

um how can i enable that? i tried to use mod_ping in prosody and activated in my config. but still my pings receive service-unavailable.

no not on the server

your library needs to enable it on client side

or maybe its enabled by default, i have no idea, on my library i have to set a interval and need to enable it

ok so i will look for xmpp.js keepalive instance, i assume it sends ping stanzas by time?

you dont need to do that with websocket

the websocket protocol has a ping/pong backed into the protocol

it is under the xmpp layer

before you spend time on that

i would look into the debug log of the server

im pretty sure it tells why it sends a close

oh wait

now i see it, client closes the connection

?

SENT: <close xmlns="urn:ietf:params:xml:ns:xmpp-framing"/> doesn't that look like the library is sending the <close/>? ✏

are you sure this is not in response to a server close

no

the message was for mbt :)

yes i guess library is closing but im not sending close

maybe talk to support for xmpp.js?

yes i think i need to do that but first i wanted be sure it isnt a server side thing

thank you for your helps guys

maybe sonny can answer me about why im sending this close stanza?

what prosody version are you using mbt?

there was a bug with invalid pong responses in prosody recently

0.11.3

that would be a reason a library closes the connection

Zash? can you comment in what version the websocket pong fix was included

0.11.5 IIRC

yes i guess it is a bug, i saw something about it

https://prosody.im/doc/release/0.11.5#minor-changes

okay thanks i will try tu upgrade
