plus.net won't open in Chrome

[#1]

Access seems to come and go. Last week I managed in Android Chrome, this week, back to the error. As you say community site is always OK and Edge, or DuckDuck browsers can get at the main site all the time, just Chrome on various OS.

I'm now getting this but only in Chrome on my Samsung tablet. My phone is fine and that's using exactly the same version of Chrome. The Samsung browser works fine on my tablet.

It's only for the main plus.net site, the community subdomain works fine.

Any ideas? I've already cleared down all cache in Chrome.

I have noticed the main site reports that it uses TLS 1.2 whereas this page uses 1.3. Don't know if that's part of the problem.
