Build 21301 fails to connect to SSL MQTT

See original GitHub issue

I was part of the beta of OwnTracks on the Play Store. After the update of yesterday, my OwnTracks client ceased working immediate. It simply wouldn’t connect to my MQTT server anymore. It only showed “error” in the app, but unfortunately didn’t show any details

After exporting the config, leaving the beta, uninstalling, reinstalling the stable version and importing the config it works again as it did before.

With the new version (build 21301) my MQTT server reports issues with SSL:

1551816331: New connection from X.X.X.X on port 8883.
1551816331: OpenSSL Error: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number
1551816331: Socket error on client <unknown>, disconnecting.
1551816341: New connection from X.X.X.X on port 8883.

1551816412: New connection from X.X.X.X on port 8883.

1551816412: OpenSSL Error: error:140940E5:SSL routines:ssl3_read_bytes:ssl handshake failure
1551816412: Socket error on client <unknown>, disconnecting.

This works just fine with the previous build, 21201.

As MQTT server I’m using Mosquitto 1.4.8 on Ubuntu 16.04 LTS.

App build number: 21301
Android version: 9
Device: OnePlus 6T

Try to change ‘Common Name’ to proper one or try LetsEncrypt cert for mosquitto. One of these would be solution i guess. I bet the last one. I can confirm, i had also issues with the newer version of the app, but after putting my LE cert into mosquitto and restarting the container its ok now. (i just need to reconfigure android client also, because new cert, previously i had self signed and had ca cret installed on android).

I was surprised by the number of testers myself. Glad it is working as expected now.

Thanks for uncovering that change in behavior. I’ll add a warning to the release notes of the public version.

Issue will be closed as everything is working as intended.
