I tried out the #ooni network tester app from #FDroid. I have good connectivity here in #Malaysia, both from a cellular SIM card connection, and the monastery wifi (a fiber internet connection).But alas, the Ooni tests don't test for #XMPP, in their instant messaging apps testing! Only #Facebook, #Signal, Telegram, and Facebook Messenger are tested for, apparently. I do have trouble with XMPP, on the fiber internet here. Insidiously, brief XMPP text messages can be sent, but any video memo (say, 40MB in size, about 4 min worth of video) will only 1% upload, then get stuck. Attempts to resend will keep getting stuck. It seems that the XMPP traffic gets throttled to nothing after a small amount of data is sent: say, 400kb or so. I *can* send these video memos from my cellular SIM card connection.I wish Ooni could have warned me about this, as it caused a friend to not receive a video memo for about 10 days, until I caught on to what was happening.

@sbb Attachments are usually not sent directly in XMPP messages, but uploaded to an HTTP endpoint. You might want to find out why that is failing.

@raucao it uploaded to the XMPP's server's port 5281. It's a #prosody server which I run.

@sbb @raucaoI strongly suggest to run both xmpps-client and HTTP upload (and BOSH and websocket, if we are at it) all over 443.No idea, if it would have helped in your situation, but it helped me a lot, e.g. in British trains.#Jabber #XMPP

@debacle @raucao any tutorial for that, which you can link to?

@sbb @raucaoI copied my #nginx configuration from here:https://wiki.xmpp.org/web/Tech_pages/XEP-0368#nginxAlternatively, you can use #sslh, but I don't have any experience with that.

@debacle @raucao Thanks for that, but I'm puzzled how the various #XMPP-related hostnames (like upload.example.com, proxy.example.com) get assigned/bound to different kinds of traffic in that nginx config.

@sbb @raucaoThat's just the "normal" #nginx domain, location and #reverseProxy stuff. I don't have a good example at hand (we have it at work, but the git is not yet public, sorry), maybe others can point to a good tutorial?@prosodyim maybe?(Reminder to myself: Put more $dayjob stuff to the public git. There are no secrets anyway.)#Jabber #XMPP #prosody

@debacle @raucao @prosodyim I'm OK with all these hostnames being split up in XMPP, but as to using all those non-443 ports... sooner or later, a "standard" #XMPP server will surely heavily use ALPN and port 443.

@sbb @raucao @prosodyimUnfortunately, public wifi and other badly configured #firewalls killed the concept of TCP ports. There is only one port left, that's 443 for everything.Some people argue, it is a blessing for #privacy, because all our criminal #Jabber usage is hidden now.

@debacle @sbb Honestly, I'm not sure what you're talking about. I travel around the globe *a lot*, and I have more issues with centralized services being blocked than I ever have with standard XMPP ports. I can't even remember the last time I wasn't able to use XMPP on standard ports without a VPN.

@raucao @debacle Another anecdote: A friend of mine in the #Philippines couldn't connect to my #XMPP server in #Singapore, *until* he turned on a VPN with an exit node in Singapore. There's all sorts of strange QOS rules lurking in the various ISPs' routers here in Asia.

@sbb@c.imWeird, I never had issues to connect to my #xmpp|d from the #Philippines (also worked well from #Vietnam, #Malaysia, #China and #Taiwan via standard ports. I only had to use other ports or #Tor in some shitty airport wifis.@raucao@kosmos.social @debacle@framapiaf.org
