TLS security setting

Use SSL 3.0

Use TLS 1.0

Use TLS 1.1

Use TLS 1.2

It is many years since SSL 3.0 was shown to be insecure. Please remove it from the list - it should not be enabled.

We appreciate your response and the confirmation. To troubleshoot, we suggest the following steps:

1. In the Windows Search bar, type Internet Options.
2. Open the app and got to the Advanced tab.
3. In the Security section, scroll down and add a checkmark to the following:                                                                                                            Use SSL 3.0

Use TLS 1.0

Kind regards.

I have been trying to figure this out for days. I seen this info and I fixed it in 20 seconds!!! TY so much!!!! Tammy

I was able to finally FINALLY FINALLY fix the problem. Yes, I tried all of the TLS and SSL check marks and unchecks. 

Automatic updates review

Restore points

Different browsers (FireFox, IE, Edge, Chrome)

Resetting TCP/IP

Resetting Winsock

Clearing Browser History

Changing DNS settings

Testing TLS/SSL Browser settings on other sites confirmed all ok

Looked at the CERT, noticed it does not cover the domain WITHOUT the WWW but didn't make a difference and imported the CERT as well. For example...

https://domainnamehere.com instead of https://www.domainnamehere.com  where the cert only covered other variances but not without the WWW but didn't make a difference.

Yes, tried the IP address directly avoiding DNS

Scanned for viruses

Downloaded Malwarebytes just in case and ran another full scan and scanned for rootkits

Cleared DNS cache, pinged DNS name, confirmed IP was correct, confirmed DNS had the correct entry

...and more, etc etc etc...

I was getting a bit frustrated and this is a fairly new install of Windows 10 just 3 weeks ago for a client and I absolutely did not want to start all over again so I troubleshot this for HOURS and took on HOURS more unbillable as I felt sorry for the client.

The workaround is using TOR. I used a TOR browser and I connected fine. Curiosity kicked in and I continued to troubleshoot....it was the antivirus. The same AV that has been running since day one. The same AV that ran on his Windows 7 PC prior to the Windows 10 migration. Accessing the same website as he always has for many years which is a government site required for his business. No idea why it just stopped all of a sudden but once I disabled the antivirus software, it started working.

Hello Jward47,

I'd like to get more information regarding this so we could further check and provide a more established workaround.

Any changes made to the system that might have caused the issue?

And do confirm the current build your Windows 10 is running, as this information is vital for us to proceed with the investigation. (Type winver into the Cortana search box, then hit Enter.)

Also confirm if this only affects certain websites and if said sites are accessible using different browsers.

We'll need you to confirm this first before we proceed, thus we highly recommend that you send us a screenshot of complete error message.

We will keep an eye out for your response.

Regards.
