lelapin Posted July 10, 2022 Share Posted July 10, 2022 (edited) This morning when trying to access several websites that I normally access daily with no problem including this one I am getting the following message. This happens even when I switch to a different browser. When I switch to my Thai VPN all works OK. Any ideas why this is happening.

Quote Thai VPN You use a VPN to generate another Thai IP address? Sometimes the root cause is a wrong date/time on your device. Have you checked?

The OP has a technical problem with his device/browser/"addon"/"security SW" whatever. It could be related to a blocked website actually. If their ISP is dns hijacking to block a website the browser certificate authority will report it as untrustworthy/insecure. Similarly if an authentication server is down, a certificate expires, or they just use http instead of https this could lead to website issues like this. Of course it could be a client-side issue as well like incorrect date/time, antivirus complications, etc. They haven't really given us enough info to fully troubleshoot but based on it affecting a lot of sites and being alleviated by a VPN connection - if they haven't recently had any changes (new programs, new network, etc) I'd wait a day and see if it's just an ISP hiccup.

Is it a home network? Do you own it? Is there a captive portal to log in? Which ISP do you use? That sort of thing. Another client-side troubleshooting step, you can try manually setting your dns to 8.8.8.8 and 8.8.4.4 and see if bypassing the ISP's dns solves the problem. If you're using a separate antivirus program make sure to turn any "scan ssl" type settings off and test if that fixes the problem. Link to comment Share on other sites More sharing options...
Mutt Daeng Posted July 11, 2022 Share Posted July 11, 2022 (edited) This problem is sometimes caused by the windows date/time being set incorrectly.

I am using TMN network from home on my own private Acer laptop. I only use Microsoft Edge antivirus. I am over 80 years old so find trying to solve this problem quite stressful but at least I can operate OK using VPN to Thailand/ Uk depending on which site I am visiting. What puzzles me is that it might work OK on a site a couple of time and then on that same site I will then get the warning.

fdsa Posted July 12, 2022 Share Posted July 12, 2022 > CERT_AUTHORITY_INVALID something is messing with the SSL encryption. Either the internet provider is trying to hijack the httpS traffic, or some program (possibly malicious, sometimes it is an antivirus) messed up the embedded list of SSL certificate authorities in your browser or/and operating system. Sometimes it is the wrong time and date - e.g. if the SSL certificate is issued in year 2022 but you have year 2010 set on the computer then the certificate is treated as invalid because your computer sees it as "not issued yet". But this seems to be not your case. Try to use a different browser.

lelapin Posted July 12, 2022 Author Share Posted July 12, 2022 Thanks for all the suggestions / ideas but I do not understand why all is OK when I am using VPN linked to the UK or Thailand. Although it is a little slower I think I will keep this on now all the time. Link to comment Share on other sites More sharing options...

Although it is a little slower I think I will keep this on now all the time. When you use most vpn programs you bypass your isp's dns automatically along with most of their other filtering methods. They just see an encrypted connection come from your ip and go to the vpn server's ip, your vpn provider then handles everything else. The fact that your vpn fixes the problem suggests that the problem takes place somewhere after the vpn is in the mix (i.e. your network or further down the line with your ISP). The first step as I said before should be bypassing your isp's dns in favor of something like google's. Here is a guide. If that fixes things then you would know it's a problem with your isp's dns.
