Teamcity as Symbol Server no pdbs found

Question

I am trying to use Teamcity as Symbol Server. I set Up TC like I should and TC is indexing my files.

I found THIS question so I tried it to find the symbols on the server. I get some .dll listed with the command symchk /r * /s SRV*http://outserver.acp.net/app/symbols. I Only see other dlls but not my libraries or pdbs.

What did i miss?
