This problem is very random. I can be on a site and suddenly get the time out error when navigating to a new page on the site. One particular site that I have used in the past will never open now. It is https://pixhost.to/ That site worked for me only 4 days ago. Now I cannot open it. I get the following error message on FF - "The connection has timed out The server at pixhost.to is taking too long to respond. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer’s network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web." I am using Win10 Version 1803 x64 - using Firefox 61.0.1 64 bit Here is a partial list of the fixes I have tried to use either on my own or with remote assistance with MS tech people - Checked on "Is It Down" website to make sure the site was up and reachable Completely cleared all cache, history, coolies, etc. Called my DSL provider to reset and test my modem. Unplugged my modem and restarted it manually Complete reinstall of Win 10 - TWICE Turned off virus and firewall protection Opened new InPrivate session Done a network reset Added sites to exceptions rules in browsers and firewalls. Reset browsers Ran and completed MS tools for updates, drivers and system Ran in safe mode Uninstall and reinstall network drivers - tried old drivers and new Changed DNS settings from the default setting of "obtaining DNS server address automatically" to a set DNS address of "8.8.8.8" and "8.8.4.4"  Used command line as admin to do a ipconfig dns flush ipconfig /registerdns ipconfig /release ipconfig /renew NETSH winsock reset catalog NETSH int ipv4 reset reset.log NETSH int ipv6 reset reset.log Tried to ping several websites that were unreachable and immediately got “request timed out” as the result Same sites do not open on Chrome, Edge, Explorer and Firefox Ran Malwarebytes and a few other tools to clean registries and check for issues Started a “Test” user on my computer to start a clean run and navigate as a new user Rolled back the latest updates made to Win10 – a MS tech did that Well that is the main things that have been attempted to fix this issue and none have worked. I probably forgot a few things that were tried. Can someone please help? This is very frustrating and time consuming. I would love to browse like normal again. Thanks
