Windows Forum Not Secure Message


Recommended Posts

Just tried accessing with 5 different browsers - IE 11, Firefox, Pale Moon, Commodo Dragon + Eclipse - none of them give me any message like the one you quote ! :biggrin:

Possible reasons ?

 

(1) Error in your system's date, time, or time zone, which throws off certificate validity checks.

Sometimes allowing computers to use an internet-based time source can introduce this problem.

 

(2) Firefox not being set up to work with your security software that intercepts and filters secure connections.

Products with this feature include Avast, BitDefender, Bullguard, ESET, and Kaspersky; AVG LinkScanner / SurfShield can cause this error on search sites.

If you have any of those specific security products: check this support article: How to troubleshoot the error code "SEC_ERROR_UNKNOWN_ISSUER" on secure websites.

 

(3) On Windows 10, Firefox not being set up to work with the parental control software Microsoft Family Safety. (To test by turning it off, see: http://windows.microsoft.com/en-us/wi.../turn-off-microsoft-family-settings)

 

(4) Malware on your system intercepting secure connections.

 

Are you using the latest version of Firefox ? - should be 53.0

Boris,

Thanks

 Ref your ideas:-

1 No error in date/time

2 Using AVG but not Link Scanner

3 Don't think so

4 No Malware on Computer, scan daily with AVG & weekly with Malwarebytes

5 Yes Firefox version is 53.0

Do you suggest binning last Bookmark & setting up again?

Saw this a couple of times but only with Vivaldi, no other browser had any problems and Vivaldi has since gone back to normal without any input from me.

Thanks.

I'm OK now

Vivaldi must have had an off Season!

I'm seeing the exact same problem with 32-bit Firefox 53.0 under 64-bit Windows 10 Pro (v 1511). None of the possible solutions / workarounds had any effect. I had no choice but to force a dubious "bybass".  This is one of only 3 sites I've ever seen this error with, and so the presumption exists that the warning may well be legitimate.

 

FYI.
