[Bug]: Monal to Monal OMEMO encryption doesn't work about monal HOT 11 CLOSED

The server is too old, pubsub (which is used for omemo) won't work properly on this server. Please use at least ejabberd 23.10, as per https://github.com/monal-im/Monal/wiki/Considerations-for-XMPP-server-admins
The yellowish XEP-0163 entry in your screenshot indicates this, too.

Why is omemo working between Monal and other clients?
Because omemo is self-healing and if one device can get the keys of the other device an encrypted session will be created, but between Monal <--> Monal on the same old server, none of the two clients is able to get the keys of the other party, so no one is able to initiate the encrypted session.

Use backports for Debian to get recent enough versions and bugfixes!

I added a workaround in dd64357 that will make it into the 6.4.2 stable coming out in a few days.

Please send in logfiles of both iOS devices to debug this further: https://github.com/monal-im/Monal/wiki/Introduction-to-Monal-Logging

Send them via email to [email protected] and include the jids of both accounts.

Done.

I sent you the log files from the one iOS device and the macOS device. I don't have access to the other iOS device.

That's okay, thanks!

Can you tell me which omemo deviceids the two devices you sent me the log of have?

from monal.

The current** ones are:

• iOS: 520568234
• macOS: 1645153921

** I used to delete and re-add the account on the iOS device in trying to resolve the issue, which regenerated the device ID IIRC

from monal.

ah okay, then this ids won't be of much use...

What exactly do you mean by "delete and re-add the account"? You removed the contact or you removed the entire account on the device (under Settings --> [your account name] --> Remove Account from this Device) so that monal was fresh?

Can you provide a screenshot of the server details of your server (Settings --> [your account name] --> Protocol support of your Server)?
