Hi,
I use Jira-Cloud and tried to upload app on May 13, 2021 (GMT) using UPM that is required to input the URLs for the app (https://subdomain.mydomain.co.th:61111/twpconnector). The error message was shown below.
The last installation with this URLs worked properly for 3 years ago but I uninstalled this app and tried to upload the new one to support the new issue view GUI and face the problem.

I can access via web navigator with the URLs above, but in Jira cloud instance it can't.
Can I get the log file to investigate this problem? and How?
Can everyone advise me how to solve this problem?
Thanks,
Soraya
