[SOLVED] How to create room with jwt in authentication token mode?

Hi I have integrated with JWT and it was running also properly but today when i entered into room i got message “Authentication failed”.When i checked the error log i found in prosody log i.e:-“General warn Error verifing token error not-allowed reason:not acceptable by exp”.Please help me regrading this.

exp is the expire time. Seems that the token is expired. Create a new one

Okay . Thank you.
