If I attempt to use SSL to connect to this site ( https://community.smartthings.com/ ), Firefox responds with the following:
community.smartthings.com uses an invalid security certificate.
The certificate is only valid for the following names: forum.choiceofgames.com, choiceofgames.com
(Error code: ssl_error_bad_cert_domain)
I am seeing the same thing.
They have a wildcard SSL, which is active on shop.smartthings.com. So they just need to get something cleared up with whoever hosts their forums.
This has been happening for the last week. IE will let you bypass the cert error but Firefox does not. It is complying with the siteās specs.
This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox only connect to it securely. As a result, it is not possible to add an exception for this certificate.
I figured after a few days this would get sorted out. This happens on every PC in the house but oddly, not on the phones.
Anyone else see this happening or do I have something crazy going on?
It has been happening to me in Chrome on my Android phone, but not Chrome on the PC browsers.
Sometimes it works on the phone, but it is only about 1 out of 3 attempts. It has only been happening to me for about the past week.
I had the same thing, but the issue seems to be resolved as of yesterday.
I was reading this since Comodo PositiveSSL seemed to be the cert issuer.
I have this issue on my Android not just this site but many others.
What version of Android is this? What browser are you using?
Iām on Android 5.0.1 on a Tab S and Chrome on the latest stable versionā¦ and I have those errorsā¦ but not on Windows nor MacOSā¦
Can someone actually post a screen shot of the full error they are getting please.
Thank you, when it does that, can you click on the red padlock and you should have a details link, click on that then click on āView certificateā and finally go to the āCertification Pathā tab.
Can you grab a screen shot of that please.
Looking more for the full chain to see where itās breaking down but just noticed that Chrome on Android, lemmie just check how to do it on Android.
Okay, kinda the same, see the drop down arrow near the top next to ācommunity.smartthings.comā on that same āCertificate Viewerā page, click that and take a screen shot.
Thanks for your help.
Okay, so it looks like itās breaking down between the intermediate cert and the root cert, if you tap on the "COMODO RSA Domain Validation Secure Server CAā, what does that page look like?
Okay, that seems to match the serial / fingerprint of the intermediate certificate Iāve got so either the root certificate is not being sent with the rest of the chain or itās corrupted somehow.
Given that people are only experiencing this on certain browsers/systems, whatās weird is that it works fine on my Android 6 phone with Chrome. Iām guessing the site isnāt supplying the root certificate and some devices donāt already have it in their Trusted Certificates store on their device.
Without having a device where I get this error, itās harder to diagnose further but thank you for the help @danielccm!
@discourse @codinghorror is this something you need to correct or SmartThings staff?
@Benji if you tell me what else to do, Iāll gladly do it! Iām sure we can diagnose it completelyā¦
I like your enthusiasm! Unfortunately it gets a lot more convoluted for little extra gain and ultimately, we canāt fix the error.
Well, you might be able if it is what I think it is but telling people to install certificates into their trusted certificate store would be dead against ethics and having people listen to that kind of advice from strangers is a sure fire way to get their devices horribly compromised, so letās not 
If anyone tells you to ājust add this certificate into your trusted certificate storeā, politely tell them to go and pound sand.
