[Bug] Error: certificate has expired

[nowherex]

Hi everyone, I recently started getting the following error: "Error: certificate has expired", but my certificate is not expired, I even renewed it (letsencrypt) and the error persisted, tested it on another mqtt broker (hivemq.com) and got the same mistake.

is there anything that can be done? I would very much like to continue using this fantastic tool, as I also use the emqx broker, thank you.

Environment

• OS: Linux Mint
• MQTTX version, Version: v1.6.0 and Version: v1.6.1

I'm not sure if this is a repeat of #721. Could you please test it on an older version, like v1.3.0?
Maybe you could post a reproduce detail.

Thanks for your feedback!

Hi @oceanlvr and @nowherex!

Could this problem be related to: electron/electron#31212? I'm seeing the same error connecting to my own MQTT broker (Mosquitto behind Traefik with a valid Let's Encrypt certificate) and the same happens to the "MQTT Explorer" client, which is also build with Electron. In fact, I came to your client after seeing that "MQTT Explorer" was failing and the truth is that I am thinking of migrating, because your UI is excellent.

What version of Electron are you using? They seem to have released patch releases for Electron 12, 13, 14, 15 and 16.

Thank for your help and best regards,

Aitor

@bodiroga @nowherex Thanks for your support, I'm tracking this problem.

What version of Electron are you using? They seem to have released patch releases for Electron 12, 13, 14, 15 and 16.

https://github.com/electron/electron/pulls?q=Root+CA+X3

https://releases.electronjs.org/

MQTT X's electron version is 11, and it seems that the electron team doesn't patch for the 11 version.

I'll reproduce the issue and determine that this problem is caused. If possible could you please help us test this problem?

I think you could upgrade the electron to the 12~16 latest patch version on the master branch.

Hi @oceanlvr!

Ok, good news, here you have what I have done and the results I got:

• Clone the repo (master branch).
• Install yarn and electron-builder (I didn't have them installed). I have to note that the "node --version" command prints that I'm working with the 15.4.0 version, not v14...
• Edit the package.json file and modify the "electron" dependency to version 12.2.2.
• Execute the "yarn install" command to install all dependencies.
• Execute the "yarn run electron:serve" command to launch the app.

After that, I tried to connect to my MQTT broker (Mosquitto behind a Traefik proxy with a valid SSL certificate) and... it worked! 🎉 Awesome! But... I don't know if upgrading to Electron 12.* will have any side effect consequence, although in my fast tests I didn't notice any error. Subscribing to # and publishing some messages worked fine 😉

I hope this information can be of any help to you 👍🏻

Thanks again for all your work and best regards,

Aitor

@bodiroga good job! Very happy to receive your feedback, 🎉 🎉 🎉

Because upgrading to the new electron version is a free change, I may need more testing to officially push to release, thanks for your work! 👍🏻 👍🏻 👍🏻

@bodiroga Hi! I have been tested this upgrade, version 12.2.2 works for me.
We are delighted that you are a contributor to MQTT X, so could you please PR to the master branch? I am very happy to receive your contribution!
Thank you so much for your help and feedback!!!
