I"m trying to setup a database connection to DB2 under Database. Intellij Idea is trying to download a jar file to set up the database connection but getting some error. I tried to download the same jar from browser, it was downloaded successfully. I dont know why Intellij Idea is unable to download the files. Similarly while grails is trying to download some jar files from grails site intellij fails to do but I'm able to download separately from browser.
