Hello @Jackson
We are glad that the issue is solved.
the effective time of JWT is a month and a year in 1980!
It’s a little bit strange. But in general, leeway parameter is used in case of time difference between servers. We have discussed it in other topic recently: Error when trying to connect (Error occurred in the document service: Error while downloading the document file to be converted.) (version 7.2.1.34) - #25 by Alexandre
Anyway, please feel free to contact us if you face any issues.
