I used to find all sorts of problems at work that other computers could not refresh, and that on a very tightly-managed, very secure system! Perhaps I ought have a retirement occupation as a test-consultant finding obscure snags the IT professionals need to correct.
I encountered another site giving that unable-to-find message with its recommendation to turn on three settings called "TLS". I found that on my PC they are already ON.
So… now what?
Luckily I found a Microsoft site (No I can't recall its name or location) that explained that as the original "not found" message hints at; fairly recently MS changed Internet Explorer to overcome a flaw in the security method once common in web-sites.
I don't pretend to understand it fully but essentially, the basic message is that IE will block a site still using that security system.
…
I tried the SLS switch – no change, so I reversed it.

For the router, I recall its supplied instructions say leave it turned on, but only for unspecified "up-dates". …
I don't like leaving electric / electronic appliances live when I not using them, and indeed have not installed a new caller-ID telephone I'd bought because it too apparently needs mains power all the time.
Curiously my start in computing was in testing due to a strange ability to find bugs others missed! You might have missed an opportunity to make a career out of breaking computers like I did.
Anyway, I think the once common problem you're describing is a group caused during development of Internet encryption. It didn't arrive fully functional and secure, rather it developed through several painful steps. The first encrypted web-sites used SSL2.0. After several hundred million people were happily using it, a number of vulnerabilities were discovered and SSL3.0 was issued, but that turned out to be faulty too. As the internet expanded more problems were discovered and a major upgrade called TLS started to replace SSL starting in 1999. TLS changed enough to be incompatible with SSL and has itself gone through a series of upgrades, currently up to version 1.3
Here's the problem: in order to communicate securely, website and browser must both support compatible encryption. When a major component like encryption is upgraded it can take several years to make the change. Not everyone is keen to upgrade, and no-one likes spending money if it can be avoided. SSL3.0 ran in parallel with TLS until 2014 allowing 15 years for everyone to convert. During transition there was an ever decreasing need for some users to run SSL. In 2019, I would need an extremely good reason to connect to any internet website still using SSL because failing to change by now shows a negligent approach to security!
One way of getting into trouble is by embracing change too early and finding all the bugs, the other is to stick in the mud with an increasingly outdated system until it becomes incompatible.
Although your error message occurs if there's an SSL/TLS mismatch, I don't think it's causing your problem because tractionTalk is using TLS. Something else is causing the same symptom. Likewise, I don't think Internet Explorer is guilty either. Although Microsoft still support it, IE isn't being developed: it's being replaced by Microsoft Edge. If something changed on IE, it's probably only fixing a security hole you don't want. Although Microsoft were heavily fined in the past for breech of monopoly law by corralling users, IE is no longer a major Browser, down to about 6% this year and falling rapidly.
The history of your machine has been turbulent: upgrading to Windows 10 and reverting back to W7 is a major adventure. It's possible you have ended up with a slightly corrupt W7. Mending slightly mangled computers at work was easy: all data was stored on a server, so all that was necessary was to blow a new copy of the entire operating system on to the machine from the gold master disk. This contained a fully tested copy of the operating system, device drivers, standard applications, and all configuration settings. No one had to think! In comparison domestic systems are far more difficult: with limited support the owner has to diagnose faults and fix them without damaging data or anything else. Registry settings are horrible, and Malware is an unpleasant possibility too. Took me 3 days hard slog to fix my daughters computer when she got home from University. Might be easier to pay for a suspect machine to be checked professionally.
My mum likes turning everything off: she's green and thrifty. I had a hard time persuading her it's not a good idea to turn off devices like her TV and router that upgrade themselves overnight! What happens if you do is the device might fail because it's no longer compatible with base, or because a giant stack of upgrades builds up and the install times-out because it takes too long. Little and often is best.
Hope that helps,
Dave
