DNS resolving 0.5.0 issue

after installinf firmware 0.5.0 on mangOH yellow DNS is not working.
/etc/resolv.conf is broken symlink to /var/resolv.conf
how to fix it?
what is correct contents of resolv.conf ?

Generate new resolv.conf to replace /etc/resolv.conf. And add your dns server inside resolv.conf.

thank you!
I have already solved issue. That helped me:
