Why routing run failed

Summary:
Routing run status: Failed
Description: Routing Plan Timeout expired. Please consider increasing Time Limit value.
Assignment will cause link constraint violation.: 5
Assignment will cause Resource Preferences violation.: 1
Field Resources calendars and activity windows do not overlap.: 6
Routing run start time: 21/01/26 05:00
Routing run end time: 21/01/26 05:37

But we have given routing run time limit is 30 min
then why it takes 37 min to run?

Description says Routing Plan Timeout expired. Please consider increasing Time Limit value.
But still the question is why routing run for more time also run failed and do not assigned any activity to resource?
