Unable to access the Admin page of my modem router since latest Windows 10 update

Since I updated the latest Win 10 update, I am unable to access my modem router's admin page. I previously never had any problems logging to the admin page. I took the extra step of uninstalling my antivirus/firewall program and logging in to no effect.
I can access the internet and have no issues in viewing any website. The only time I have been able to access the modem router admin page since the last Windows 10 update is when I start windows in Safe Mode with networking. Refer message below:

Your Internet access is blocked
Firewall or antivirus software may have blocked the connection.

Try:

• Checking the connection
• Checking firewall and antivirus configurations
• Running Windows Network Diagnostics

ERR_NETWORK_ACCESS_DENIED

Check your Internet connection
Check any cables and reboot any routers, modems or other network devices you may be using.

Allow Chrome to access the network in your firewall or antivirus settings.

If it is already listed as a program allowed to access the network, try removing it from the list and adding it again.

W10 can connect to wider internet but cannot access web pages

I have an odd issue with my W10 laptop linked to Sky broadband in the UK via wifi using a Sky router. The effect is that while I can actually access the internet (I can send and receive emails using Outlook and can connect to other machines using TeamViewer) I cannot access any web site (Google, BBC etc). There is no specific error message, merely that the access request timed out and a suggestion that it may be to do with proxy.

I have tried the following:

1. Other systems (W10 and ios) can access web sites using the same Sky router (therefore probably not a router problem)
2. I have sent and received emails using Outlook, so the broadband connection is working (probably not a Sky problem)
3. I have tried two different browsers (Firefox and Edge), no connection (not a browser problem)
4. I am using Windows Defender and have:
   1. Made sure that Firefox is in the list of allowed systems in its Firewall, no connection after a reboot
   2. Turned off the Firewall and tried again - no connection

My next step will be to re-install Windows, but has anyone got any other suggestions? Could it be some sort of virus (I have carried out a complete virus check using Defender)

So - any suggestions?
