ROS v5.26 on x86 Upgrade issues

Hii there, please i am having difficulty upgrading ROS v5.26 with L6 license running on x86 a pc. I get the error “could not resolve address upgrade.mikrotik.com”. Please I would appreciate suggestions such that will help secure license. Thanks

Are you sure you have configured DNS servers in IP->DNS on the router?

Try to open upgrade.mikrotik.com in a browser on your PC. It should take you to MikroTiks main page.

You should also be able to upgrade manually by download files.

If your device is connected on internett, I would not have been shocked if your router was hacked.
Running an more than 8 year old software (5.26) put you at very high risk.
