I have a user who is receiving "We couldn't create the subtask. Check your connection, then give it another try", when attempting to add a subtask to a software project board. Any ideas on how to tackle this? User is able to traverse Jira in every other regard.

I ran into the same issue today and upon investigating further I realized the root cause is due to the new issue view. When you try to create a Sub-task against a jira issue with no existing linked issues and if your Sub-task create screen has mandatory customfields, then you will see the below error.
This worked for me and I hope it does for you as well.
Welcome to Atlassian Community!
I understand that a specific user is facing an error when trying to create a sub-task from a specific issue in a board. Is it correct?
Please, provide us the following information so we can better troubleshoot the problem:
- Are there any other users facing the same problem?
- Is the problem happening when the user tries to create the sub-task directly in the issue instead of using the board like in the screenshot below?
- Is the problem happening only for a specific issue in the board or is it happening for any issue?
- Can you confirm if the sub-task issue has any required fields? The following bug causes an error if you try to create a sub-task with required field:
Let me know if this information helps.
Thank you for the information.
Since you are being able to avoid the issue outside your network, I recommend you to check with your infra team if the Cloud IP Addresses and Domains are properly whitelisted in your firewall and proxy:
Once you whitelist it, please let us know if the problem keeps happening.
Hello @Bryan Bellamy
Investigating a little further, I found another possible reason for the error you are facing:
If a project has a default assignee but the default assignee does not have the assignable user permission, users will be prompted with the generic error you are seeing when creating a subtask through the new issue view:
That being said, can you check if the default assignee under project settings > Details have the "assignable user permission"?
I was running into this issue myself, and found the problem in my case was that someone had removed the Summary field from the Subtask issue type. Adding that back on allowed us to create subtasks from the new ticket view again.
I found this out when I tried the use old ticket view mentioned above. I was able to get the pop up window to come up and noticed there was no place for the summary and went from there.
Hope this helps someone else.
I am having the same issue for adding any type of task to an Epic.
1. I have checked the Project Details for Automatic Assignment and this is Unassigned.
2. It is not related to "Summary" of subtask being removed - but not 100% sure how to check this.
This needs to be fixed in the new version as we cannot keep going back to the old version.
