Do you have a Time Machine backup to Restore to/from?

Or...
Make a New Location, Using network locations in Mac OS X ...
System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.
System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
The interface that connects to the Internet should be dragged to the top of the list.
Sys Prefs>Network>highlight the Interface you're using>Advanced>TCP/IP>Configure IPv4: Using DHCP.
If using Wifi, instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.
System Preferences>Network>choose interface>Advanced>Proxies Tab, make sure none are set, like for HTTP & HTTPS.
System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...

Without a Time Machine Backup at all - the only other method I know of is IF you have Bootable Clone of Mojave. Without that and no TM Backup - suggest following @BDAqua advise.
That or How to create a bootable installer for macOS of Mojave - boot from it - Wipe the Drive clean - everything will be lost and can not recover - and reinstall Mojave and start reinstalling Applications etc. from Scratch
thanks for the timely advise will try these methods and post a feed back asap.
Yes do so, if or when time permits.
@p.phillips problem solved!! thank you so much for the great advice
Welcome. Just for clarity purposes for other users, which method solved your issue ?
@BDAqua i used the last advice on the reconfiguration of the DNS and it worked. Thank for the help!!!!
