Probably an out of sync Hive node. Can you try switching to a different one in your settings?

I tried

rpc.mahdiyari.info
api.openhive.network
api.hive.blog
hive-api.3speak.tv

But still the same error. Normally is set to Auto

I was able to support the previous proposal

I used the hive blog (old ver) to vote the proposal. It worked there

Thanks !!

Are you using Keychain? What happens if you try to vote directly from this page?

I used manually the active key when I encountered the error
