Nomad agent consul token update/renew

Hi All,
I got full integration of nomad+consul+vault. Vault is running as a secret engine for consul tokens - everything works as it supposed to work. However i hit the following problem, and i can’f ind solution for it. In the nomad agent configuration, there is consul block, and there is consul token - what is the proper way to update that token not restarting nomad agent. I configured tokes TTL 24 hours, so everyday some of nomad agents are reporting “ACL not found”. Googling through the internet didn’t help, so help of the community is more then welcome.
