"Your connection is not private" prevents access to forums

[Jim Blake]

Hi - over the past few months, I've been getting this error message while trying to access the forums A LOT - 

Your connection is not private
Attackers might be trying to steal your information from forums.flightsimlabs.com (for example, passwords, messages, or credit cards). Learn more about this warning
net::ERR_CERT_AUTHORITY_INVALID
forums.flightsimlabs.com normally uses encryption to protect your information. When Brave tried to connect to forums.flightsimlabs.com this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be forums.flightsimlabs.com, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Brave stopped the connection before any data was exchanged.

You cannot visit forums.flightsimlabs.com right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later.

Any idea on how to circumvent this problem?

Thanks,
Jim

Hi Jim,

please send me a DM here to discuss this further - I believe it's on your side but we can never be too sure...

Try opening the site in a private window (Edge/Chrome/Firefox). If it works, clear your browser cache. Also make sure your PC’s date and time are correct — SSL/TLS is very sensitive to system time

Same problem here also, from time to time.

One day, all ok, another day "Your connection is not private" msg showing up.

Does this occure when you use your mobile phone? Or even on PC?

Because on mobile Phone I do get this message sometimes, too.

[Lefteris Kalamaras]

When you guys get that - can you please open a command prompt by hitting "Win->R" on your keyboard and typing "cmd", then in the command prompt, hit "tracert -d forums.flightsimlabs.com" together with a "nslookup forums.flightsimlabs.com" and post your results here.

That should help diagnose the issue.

Only do it when you see that problem however.

I'm on PC only on this forum.

And on mobile phones?

Glad it's not just me, @Lefteris Kalamaras.  As you said when I did the trace route before, the route was correct.  It's happened for the last 3 days in a row.

Thx,
Jim

hello,

since this is a potential issue with nameservers and/or routing, I need what I asked for in my previous post, so I can report it toi our ISP for further analysis. Without that, all I can do is nod my head in compassionate understanding.

Hi Lefteris - here is the result of both....

I can get to your forums now, obviously.

I'd love to get the tracert results the moment the issue happens. On our end, I've verified that all our SSL certificates are up to date and correct, together with intermediate authority certs.
