Great, thanks for the stacktrace. Makes it much easier to fix the issue.

Can I assume that you tried to connect via websockets?

Mit freundlichen Grüßen / With kind regards Alexander Rust

Thanks for creating the issue. Effectively, I try to connect through Websockets on my personal server (Debian Jessie / Nginx 1.8.1 as a proxy). I use Let's Encrypt certificate on a subdomain to reach mosquitto 1.3.4, without TLS at the moment.

binarybucks commented 8 years ago

@stephanepechard this seems to be a Paho bug. Could you send your broker address to support@owntracks.org so I can try to replicate it in order to file a Paho issue?

stephanepechard commented 8 years ago

Done

heytcass commented 7 years ago

I am also having the same issue. Trying to connect with web sockets using LetsEncrypt to a subdomain through nginx. Was a solution found at all?

binarybucks commented 7 years ago

No, it is an issue in the Paho Websocket function that we cannot fix.

alanbo80 commented 7 years ago

So, as it seems to be Paho bug, we cannot look forward to get owntracks work with a private MQTT Broker using WebSockets ? Thank you.

binarybucks commented 7 years ago

Websocket connections work fine, except sometimes they don't. In that case a future Pahl version might fix it. Judging from the speed of development, it can only be a few more years.

alanbo80 commented 7 years ago

Hi Alex,

thanks for your quick response. WS work fine ? I forgot to mention i also try to use TLS && Certificates. I've just setup a WS/TLS Connection and i ran exactly into the error mentioned above. Null-Point-Exception. As i sniffed the incoming traffic at my firewall and do see no traffic related to mqtt i guess it's a client issue. So i guessed, according to a post January '17 that maybe i was hit by the same issue and the issue is not fixed yet.

A few more years ? Dooh, i hoped to get it done this week :-)

Thanks for your help.

Regards, Alex

I'm getting the same log error. Any workaround ?
