SSL error. Can't get Free Product Key

[NombreyApellido]

Windows Defender off, Tiny Firewall permits for Plan Maker, system date&time set through Windows service but I keep getting SSL error: Please check date/time and your antivirus settings

1. Please check if the date and time on your computer are correct
2. Clean your Internet Explorer's SSL cache.

Thank you for your kind reply.

System date and time is set automatically through Windows time server and it looks ok.

Even though Explorer isn't used on this system, I flushed everything as per instructions (elsewhere) on emptying SSL cache. Did the same for Firefox since it's the default browser. Also emptied everything on Edge even though it's never used

Windows defender real-time defense is set to off.

Tiny Wall firewall (I understand it's just a front end for Windows Firewall) allows all PlanMaker traffic through.

I also tried to retrieve key through TextMaker and it gives the same error.

Can you think of something else? I would really like to keep FreeOffice installed

Thanks again in any case.

Do you use a proxy server? If you do, you should set it in your system and not only on your browser.

No system proxy, though I'm using Tor Browser to post here.

Tried creating an exception for FreeOffice install folder in Windows Defender. Did not solve the issue.

I'm giving up since I'm past the trial. Uninstalling.

Thanks for your kind and timely assistance.
