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.
