Problem efter flushing av DNS Cache

Inlägg av leo1209 » tis 18 juni 2019, 13:12

Jag har använt integrity VPN smärtfritt i flera månader men fick problem på min macbook pro (kör mojave v10.14.5) efter att CleanMyMacX (https://macpaw.com/cleanmymac) körde ett "Flush DNS Cache" script som en del av sitt regelbundna underhållningsprogram.

När jag är uppkopplad mot annat nätverk än mitt hemmanätverk, som på ett öppet flygplats-wifi där jag behöver VPNen som mest, så stryps all åtkomst till Internet. Så fort jag slår av VPNen så funkar allt igen.

Misstänker att det är något som ska läggas in i search domains-rutan under DNS-inställningar (se bifogad skärmdump) eftersom jag har för mig att det fanns någon sträng där rörande integrity eller tunnelblick.

Någon som vet vad som kan vara fel?

Tack,
Leo
