Because these processes appear several times in my log ‘chrome://rewards-internals/’, Exactly these processes failed: ‘Failed to get signed tokens’.

Does it have to do with the token rewards? Because it appears that I have 9 ads viewed but I have not received the rewards in brave:/rewards for the last 4 ads. Or could you help me with the meaning of these errors?
