Hi All!

I am receiving “ERROR: file not found” error when trying to check for updates:

I have tried updating my other two RouterBoard devices (RBcAPGi-5acD2nD and RBD52G-5HACD2HND-TC), these failed with the same symptoms as well.

Starting the update check from the menu gives the same error.

Where should I look? What could be the problem?

Your DNS resolver (and possibly router) had been hijacked. Download.mikrotik.com has IP addresses (2 of them) in 159.148.0.0/16 network.

I see. From my office network it resolves correctly…

Added 8.8.8.8 and 8.8.4.4 before my ISP’s DNSs, rebooted and it works snow.

Thank you!
