My guess is that it trips over OMEMO fallback message (This is an OMEMO encrypted message). If you are using prosody I recommend you switch to mod_e2e_policy instead as this is able to properly handle PGP and OMEMO encrypted messages instead of just OTR.

Is 'require_otr' causing this to fail?

rajil on 21 Apr 2018

Can confirm this, from 2.1.1 conversations sending unencrypted messages even omemo enabled.
Rolled back to 2.0. So from 2.1.1 conversations unusable on security minded servers like calyxinstitute

@rajil So it did work on 2.1.1 ? On 2.1.0 ? On 2.0 ?

OTR was removed on 2.0.

@canary5 What device? Android version? Server? F-Droid or Google Play store? Logs? Does it do the same of other servers? (The Calyx server misses so many features, do test with one of the top ones with an all green row: https://conversations.im/compliance/ )

It has nothing to do with otr. Its a script blocking unencrypted traffic. It works perfect on 2.0beta3. I have updated to 2.1.1 and it causing problems. Seems same on 2.1.2.

All servers. On my own server with all features+otr_required script. If you click display error message, its otr_required message from that script that blocking. If i allow unencrypted traffic it works.

Seems when you introduced new setting feature about omemo on/off/default causing. Maybe first message unencrypted to test other side omemo?

Ok thank you for the hint

canary5 on 21 Apr 2018

@licaon-kter I received an Android update for 2.1.2, not sure whether it was 1.23.8 before that or 2.x releases. Nevertheless after commenting out 'require_otr' it started to work. Also enabled 'e2e_policy' as suggested above. The documentation does not mention mod_e2e_policy at https://github.com/siacs/Conversations#xmpp-features

@rajil Your server, your config, your server software docs...
