No modal field validation error messages when using JIRA and IIS AJP reverse proxy?

[Rohit Paul]

Has anyone else encountered this situation when using IIS AJP-based reverse proxy in front of JIRA: in the "Create Issue" modal (popup) window, field validation error messages (such as "Required") are not being displayed.

Field validation error messages are however displayed as expected when using the following reverse proxy setups:

• IIS ARR HTTP-based
• Linux/Apache mod_proxy_http
• Linux/Apache mod_proxy_ajp

This seems to be the case in 2 different installations that I've upgraded from JIRA 4.1/4.2 to 4.4.5 to 6.3.x and it didn't matter whether using SSL or non-SSL reverse proxy config.

Hi,

we're having the same issue on our JIRA Datecenter Edition 7.1.4 with 3 nodes. 

When we run an invalid query (Issue Browser), we get the error:
Error occurred communicating with the server. Please reload the page and try again.
Instead of (example):
The value 'CT' does not exist for the field 'project'.
At the same time we are seeing, that users are not getting the error message if the want to insert/update issues and forget a mandatory field.

If we access JIRA over the Tomcat directly, we are not facing the issue.

Have you found any solution for this issue?

As suggested by Atlassian support I made sure Gzip compression was turned off in JIRA but that didn't make any difference whether it was on or off.
