@kuba-orlik Try either Mastalab or Tusky for Mastodon. For Twidere, the priority is Twitter, not Mastodon.

It eventually worked, but is very sketchy. It's a shame, I saw Twidere as a way to easilly cross-post

[mariotaku]

"Connection timeout" error is network related. Either your network was slow or mastodon instance failed to respond.

Mastodon posting works fine for me on mastodon.social and anticapitalist.party, so I don't think this is a bug in Twidere. Also, mastodon.host failed to load in a web browser while typing this comment, so it's definitely problems with their host. Trying again succeeded, but it took some time.

我也不能发布。刷新信息正常，所以觉得可能是APP的问题

好像发布成功了。国内网络本来就不好。

I encounter this issue a lot, on my own mastodon server, and only with Twidere client. And I can reproduce especially when I have big media attached, the media upload goes well, then the posting take multiple seconds and failed with just "timeout" toast.

After digging a little I think my mastodon instance is somehow slow to respond on the post API call, so the http socket stay empty too long (processing stuff on the server side) and the java network stack close the connection too early and don't wait enough ?

Maybe we can add a java.net.SocketTimeout settings

I confirm I get a 499 Client Closed Request from nginx on the server side !

 - - [27/Sep/2020:12:35:57 +0200] "POST /api/v1/media HTTP/2.0" 499 0 "-" "Twidere/4.1.4 okhttp/3.12.12 Android/10"

https://github.com/TwidereProject/Twidere-Android/blob/aba0d0be0e1a489f319de5abc937ff1337b24d0c/twidere/src/main/kotlin/org/mariotaku/twidere/util/HttpClientFactory.kt#L191-L211

So If I'm not mistaken, we can't set the readTimeout/writeTimeout, the app using the default 10 seconds according to the documentation.
