Jira REST api intermittently returns 403 errors

[Bill Rowell]

I've been trying to figure out this problem for a while now. I have a tomcat app which retrieves a small-ish number of tickets (~300) using the REST api. It always works when I test it from my browser using the dedicated user we set up to do the queries. But when I run the tomcat app it stops working after the first couple of retrievals and starts returning 403 errors. Can't figure out why. Sometimes after I change the jira user pwd it will start working briefly and then go back to throwing 403 errors. Any ideas appreciated.

Hi @Bill

Different REST API requests could lead to different 403 root causes...

Which API calls does your app use from which version ? (e.g.: /rest/api/2/search?jql=xxx )

/rest/api/2/search?jql=project=OPS+and+status!=closed&maxResults=300&fields=summary,assignee,customfield_10100,created

thanks!
