I'm using the symbol server plugin, and had some success with the 8.1.x version. Yesterday, however, my TeamCity was updated to 9.1.1, and the plugin seems to not work any longer. I updated the plugin to the 9.0.x version (the plugin versions are listed here: https://confluence.jetbrains.com/display/TW/Symbol+Server), but that did not solve the problem. If I point my browser to http://buildserver/app/symbols/ I should get a 200 OK response (and I did yesterday), but instead I get a 404, which I believe means that the handler for that URI was not installed by the plugin.
Is there a version that will work for 9.1.x?
