My 55B6 received version 05.65.15 a couple days ago, and I agree - certificate warnings are no longer a problem when browsing.

I did not try the rooting - I don't think I left open the interpretation that I did, but to be clear - never did it. I was seriously hoping that LG might actually fix this. Even leaving Chrome 38 in place, it should be possible - really just applying the needed cert updates. I did actually report this to LG, but I am increasingly now expecting them to ignore this. I did eventually do the factory reset, and re-installed all the apps I wanted to keep, and discovered that the cert errors in the browser could now all be overridden. The TV is never going to be used for banking or email, but it does get used to browse news sites and Wikipedia. However, the other (not connected!) issue is that modern web pages increasingly push several megabytes per page, and the tv browser instance will eventually just give up and say 'too big'. If it is feeling gracious, it just restarts with only the one page - this only usually happens when multiple tabs are open or a 'heavy trail' is being left - things like a mapping site.

Did it work? Or break things for you? I suspect it will break things since... Please keep in mind - I don't use Plex, so I don't know if this will be useful to you. I ultimately found that a combination of the most recent firmware AND a full factory reset got me back to the point where I would be at least allowed to override the cert errors. This is still inconvenient, but manageable. The full factory reset is much less convenient - you better document all apps installed, and be prepared for a couple of hours to put everything back together. I have zero idea as to why this should fix anything at all. Without a browser update past Chrome 38, the value in the browser is increasingly less as more sites simply refuse to cooperate. The difference between rooting and what I have now would gain me a couple less mouse clicks, nothing more. I really wish LG saw fit to open source this, as I think the community would be capable of bringing this more up to date. But I also suspect that features such as HDMI DRM make that unworkable.

I just had a pop up letting me know about firmware 05.65.03 for my OLED55B6. Someone has to be the guinea pig to see if this updates the cert issue. Might as well be me.

It definitely is the problem. Here's what works to recreate it on my 55B6, on firmware 5.60.25. Manually set your TV clock to Sept 30, 9AM EDT (convert to your time zone if needed). Goto any Wikipedia page using the browser. Works. Manually set your TV clock to Sept 30, 11AM EDT (convert to your time zone if needed). Goto any Wikipedia page using the browser. Does NOT work, you get a security error that cannot be bypassed. Now manually set your TV clock back to Sept 30, 9AM EDT again (convert to your time zone if needed). Goto any Wikipedia page using the browser. Works again. A root cert (DST Root CA X2) expired around 10AM EDT on September 30th. Servers using Let's Encrypt certs (which includes Wikipedia) should be testable using either that root or the newer ISRG Root X1 - which, by the way, has been around since June 2015. If you have not updated the trusted root list attached to the browser since 2015, then you will see this failure, because after 10AM Sept 30th, only the ISRG Root X1 is still valid. LG has had FIVE YEARS to fix this problem before it happened.
