Allow to work through a proxy and self-signed https about desktop HOT 15 CLOSED

Sorry for late. Does --ignore-certificate-errors have effect? If so, this is adhoc solution.

from desktop.

For now, please try command line switches such as --proxy-server.

Hi there,

that doesn't quite do the trick.
I see that data is sent through the proxy when I do a reload now (my proxy
shows bytes received and sent).
But I still get an empty page.
Is there any way to troubleshoot?

Greetings,
Malte

I tried with electron-mattermost.exe --proxy-server=<IP>:<PORT> on Windows, it works. (I chose an open proxy by serching with google.)
The app won't work in your environment even if I add proxy options.

from desktop.

Do you have any idea, how I can find out, what's not working, then?
Like I said, my screen stays blank. I only see the teams I added in tabs,
but the tabs remain blank.

Greetings,
Malte

I have to check webview tag events like did-fail-load to know what happened. However, I don't know whether I can fix it.

BTW, I tried with a proxy in intranet (it requires authentication for internet). Then, I couldn't see mattermost content. electron-mattermost.exe --proxy-server=<USER>:<PASSWORD>@<SERVER>:<PORT>
It seems that Electron doesn't support all proxies.

Just an idea, how about using local proxy?

app -> local proxy -> the proxy -> Mattermost

from desktop.

from desktop.

Assuming that, I can't guess why the app doesn't see Mattermost. It's difficult.

btw, would you test this build with --proxy-server switch? It shows detailed logs in devTools console. Although, I think we will see mere connection error...

Hi Yuya,

I get a bunch of messages on the console, that don't look too good to me.
;-)
Maybe it helps...

Thank you! errorCode: -501 means INSECURE_RESPONSE (e.g. there was a cert error).

So I want to know following points.

• Are there any SSL/TLS cert issues on the sever or the proxy?
  • e.g. older version, expired cert, self-signed cert, or intermediate cert
• Can the app browse https://google.com? (HTTPS content)
• Can the app browse http://example.com? (HTTP content)

You can add a URL as a team to browse website.

Hi,

yes, the Certificate is self signed.
https://google.com and http://example.com work both fine.

Thanks,
Malte

Excuse me, what does "trick" mean? Were you able to see your Mattermost?

from desktop.

Yes. It works now.

"That does the trick" is a general saying.

So I'm sure now, that the certificate is somehow invalid.

Thanks,
Malte

I haven't know, thank you.

conclusion:

• --proxy-server=<SERVER>:<PORT> set the proxy
  • Authentication not working.
  • Electron might follow system's proxy settings. need to research.
• --ignore-certificate-errors ignores some https certificate errors.
  • When certificate is invalid (self-signed, expired, etc. The case Chrome shows warning.)
