plugins/servlet/upm not showing the plugins list


I am facing an issue with UPM ( /plugins/servlet/upm ).
I am developing a plugin, and recently updating my plugin several times.

When I browse the UPM, it does not show any content. Actually the main Ajax call to get the plugins list is failing as "aborted". I could not find any JavaScript error related to that.

The request is host/rest/plugins/1.0/ + get parameter; I can get it successfully in a browser tab. But from UPM, with Ajax call I get:

I was having this issue in Firefox during beginning of the week. I was using IE as workaround to re-install the plugin. Now the problem happens also in IE (one day before, it was fine).

I am still using Confluence 5.6.3.

There is no logs on server side about this.

Hint: now having the issue also on IE, it is reporting the following:
SCRIPT7002: XMLHttpRequest: Network Error 0x2f78, Could not complete the operation due to error 00002f78.

Any chance someone know that issue here ?

Thanks and best regards

Back to it after a while. Not sure what was happening.

We were running Confluence on Windows server behind IIS. We changed the architecture to have it running behind Apache 2.4 instead of IIS. The issue disappeared.

It seems that it was an IIS issue, not really resolved then smile



And as workaround, I can still work with the old host/admin/viewplugins.action
