Hi,

 

Both my laptop (connected via WiFi) and Desktop (via Ethernet) are not able to connect to certain websites. I get either connection timed out or cannot access, etc.

 

Some websites - www.adobe.com; www.skype.com; www.java.com

 

Browsers used to check:

Google Chrome (Newly Installed)

Mozilla Firefox (Newly Installed)

Microsoft Edge

 

Checked on my 2 Android devices connected via WiFi, these websites are accessible.

 

Troubleshooting performed:

1. winsock reset

2, tcp/ip reset

3. dns flush

4. Ran Malwarebytes on both laptop and desktop, found some and remove them.

5. Restarted both computers, restarted the modem/router

 

...and I'm still experiencing this issue.

 

I can't even ping these websites.

 

I don't know when it started, I only noticed today. As I was trying to update my Adobe software, Java, and Skype.

 

Desktop OS:

OS: Microsoft Windows 10 Pro

OS Version: 10.0.14393 N/A Build 14393

 

Laptop OS:

Microsoft Windows 10 Home Single Language

OS Version: 10.0.15063 N/A Build 15063

 

I hope someone can help me with this.

 

Regards,

Palaboy

could have a ruled created in the firewall or maybe something added those websites to your hosts file.

 

check your outbound firewall rules in windows firewall or if you have an antivirus managed firewall program check their rules.

 

also in the c:\windows\system32\drivers\ect look at the hosts file and see if you have a listing like 127.0.0.1 adobe.com or 127.0.0.1 skype.com

 

127.0.0.1 is a redirect to a non existant place.   usually you see this when your running pirated software (not saying you are) and when the software goes to look for registration information its redirected so it can't give a response that says your software is not valid.

 

those are where you need to start.

 

I know avast antivirus has some issues and you may have to create a rule to include some websites that get blocked for no reason.

Two of the three sites you mentioned have known security risks so it may be a firewall thing as mightywiz suggested. If this is by any chance a work computer they may be blocked by  the company.

You've done the first three of this set of commands, might try doing them again in this order and finish up with the winsock reset and see if that fixes it.

 

ipconfig /release

ipconfig /flushdns

ipconfig /renew

netsh winsock reset
