Yep tried everything I can think of, now including a different network with vpns uninstalled.
I must confess I can't really understand how anything can be blocking vanadium and not brave unless it is specifically set to do so or there's something wrong with vanadium.
I just noticed there is a new version of vanadium released today so perhaps that will fix it.
I must admit though I actually prefer using brave. It was my browser of choice before becoming a graphene os user and it is with gritted discipline that I continue to use vanadium - mostly because brave is so good at blocking the darned perpetual cookie pop-ups.
