В процессе I can't go to Oswald's innkeeper Jakob

[fenestren]

Hi, how can I activate missions like the one for Oswald's tavern or the ones for the Assassin's guild, please?
I'm at Chapter 5 but still the path to Oswald's tavern is closed by rocks.

Thank you.

@fenestren,
Access to Oswald's farm opens in Chapter 2. To get there you need to read the note on the notice board in the craftsmen's quarter or talk to Lares at the port.
Access to the Assassin's Guild opens in Chapter 3 after completing the quest "Missing Novices".
