Migrate Redmine to Jira connection error. Edited

박창현 I'm New Here Jun 01, 2021

I try to migration redmine project into jira.
I refer to below site to migration. (

But the progress is stopped in connection status.

I enter my redmine address, redmine user name as "admin" and redmine password of "admin" user.
When I click next button alert message occured as "Cannot login to Redmine site: Connection reset".

I attach redmine and jira log.

Our Jira version is v8.2.3 and redmine version is 4.1.1.stable.

How to solve this problem?

The "connection reset" error you see near the end of the Jira log simply means "Redmine hung up on me".  This could be down to a network error, but I'm afraid you'll need to debug this on the Redmine end, to find out why it stopped talking to your Jira (may be as simple as a timeout, if there were a lot of data, may be something else)
