Node does not start after upgrade

hello, i went to upgrade my full node to version 1.1.6 mainnet and this error is appearing "Dec 25 18:57:26 ubuntu-s-6vcpu-16gb-lon1-01 systemd [1]: waves.service: Main process exited, code = exited, status = 1 / FAILURE
Dec 25 18:57:26 ubuntu-s-6vcpu-16gb-lon1-01 systemd [1]: waves.service: Unit entered failed state.
Dec 25 18:57:26 ubuntu-s-6vcpu-16gb-lon1-01 systemd [1]: waves.service: Failed with result ‘exit-code’.
can someone help me solve?

this is too short log to understand anything. Just restart the node and see how it starts in journal

ok, thank you very much, i found out it was a password that was changed and was giving this error.
