Windows 10: WEB browsing via WiFi through AoVPN device tunnel does not work

HI,Some time ago we implemented AoVPN. We use it to access our organization and we use domain laptops with windows 10, but we encountered a strange problem on a minority of laptops. For WEB browsing we use Cisco WSA Proxy which should be available through Device Tunnel. When the laptops are connected to wifi, the WEB browsing doesn't work and we have errors on the proxy: 1683009814.530 0 10.xyz.0.230 TCP_DENIED/407 0 CONNECT tunnel://motika.mk:443/ - NONE/- - OTHER-NONE-XY_domain_auth-NONE-NONE-NONE-NONE-NONE <"-",-,-,"-",-,-,-,-,"-",-,-,-,"-",-,-,"-","-",-,-,"-",-,"-","-","-","-","-","-"

[Solved] Web Browsing Timing Out Frequently But Downloads Unaffected

Google DNS is a good thing to test, which is why it is commonly suggested. *Wink

As I explained before, ISP DNS servers can cause issues, go down, and not be updated to your device providing DNS. If you want to go a step further, login to your router and set the DNS servers uses and provides over DHCP to the Google DNS and remove the ISP DNS servers. Be done with it.

I also strongly recommend OpenDNS servers for safer browsing, especially if you're not into browsing malicious, porn or questionable sites. 208.67.222.222 and 208.67.222.222. Those are what I use at home...effective DNS filtering to keep many bad sites that are flagged with malware out of your home network and web browsers. Free and effective.

At this point if its working, I'd say use it for a day and see if issues come back...if so then the other things I suggested might be worth looking at.

Quick DNS 101

DNS = Domain Name Servers... what it does is take what you type in your web browser, or for ping, or some name domain request...take Techpowerup.com. DNS takes that and looks into an index/cache to find out what address it is...say 123.123.123.123 and then sends the reply to the ping session, web browser, etc. so you can go to Techpowerup.com.

DNS is like a phone book, you look up a person's name for their phone number to call them and connect. DNS does that for web sites and services. It is critical for web site usage where everyone can remember domain names, but not IP addresses.
