First of all, I apologize for my English. :)

I'm playing as King of Bohemia. Despite having claims in counties of Bavaria, I can not declare war. I open the drop-down and I see all the conditions to declare war with the asterisk in green on the left but the phrase "declare war" is grayed out and no way to declare war.

Instead, with Poland, I can declare war for claims of my vassals. I do not understand anything.

Has something similar happened to anyone?

Top liege?

You must declare war on the highest liege. If your target is a Count, he probably serves under a Duke who serves under a King. You must declare war on the King.

Otherwise, maybe you married his daughter. If you have a non-aggression pact with the target, you can not declare war.

I am the king of Bohemia and I want to declare war on the Duke of Bavaria, both are vassals of HRE Kaiser. I have no non-aggression pacts nor any relationship with the Duke of Bavaria.
I have several claims on counties of the duchy of Bavaria and I meet all conditions to declare war as I can see from the dropdown menu with green asterisks.

Does the crown authority (or Conclave equivalent) of the HRE permit wars between vassals?

I think as King of Bohemia, he is already the Kaiser's vassal. Very few starts have Bohemia outside the HRE, if I remember correctly.

If you have Conclave activated, did the Kaiser enforce Realm Peace?

When you get around to posting the screenshot, also consider posting a save. That way, if it's not clear from the screenshot, we can check ourselves.

Had not thought of that. I will look at it.

However, if the crown does not allow wars between vassals, the tooltip would tell me that I do not meet all conditions.
Check anyway. I know some of the tooltips for succession law got messed up in the Conclave patch, even if you aren't running it.

Finally it was the HRE crown authority that is "high" and vassals can't fight each other even with "medium". The problem is that the game does not explain that.
Oops, I used to know that. They replaced crown authority just recently in Conclave, but I am getting quite used to the new rules already. Hopefully they can rework the tool tip so people without the patch still have a sense what's going on.

Medium CA and above preventing intra-realm wars pre-Conclave is pretty well known.

I have the same problem but the HRE crown authority is low.

I can not explain it why i cant declare war ...

Please help

Most likely you or your liege has a NAP with the target or their liege. If you are a vassal you can't break your liege's NAP's in addition to not being able to break your own.
