TFS build server 2015 stuck on waiting for an available agent

Question

I am using TFS build server 2015 and I'm trying to run a build but the build always stuck on
waiting for an available agent for 2-3 minutes and then fails.
I tried to download the log.zip but its empty.

waiting for an available agent

When I run the agent from cmd the next message appears:

The Agent failed to start this job. Error: An error occurred while sending the request

I checked all the logs in the event viewer and there are no errors at all.
I also tried to re-install the agent and nothing seems to help.

My configuration process:

Edit: I found the problem. in the Team Foundation Administration Console the property of "Notification URL" was with invalid value of not existed server.

If your build requires a specific capability, then the agent must have those.

When a build is queued, the system sends the job only to agents that have the capabilities demanded by the build definition.

Check the build definition requirements and the agent offering: it is clearly described in the Demands section of documentation.

Make sure the account that the agent is run under is in the "Agent Pool Service Account" role.
Try to change a domain account which is a member of the Build Agent Service Accounts group and belongs to "Agent Pool Service Account" role, to see whether the agent would work or not.

the user that run the agent have administrator permissions on the pool – Evya2005 Jan 12 '17 at 07:25
The account need to be a "Agent Pool Service Account" role. Please double check it. – Cece Dong - MSFT Jan 12 '17 at 07:47
I dont have "Agent Pool Service Acount" the roles that i have are: -Agent Queue Administrators -Agent Queues Users – Evya2005 Jan 12 '17 at 08:02
look at the screenshot that i added, there is no "Agent Pool Service Acount" – Evya2005 Jan 12 '17 at 08:12
Please check my screenshot. You'are looking Agent Queues, not Agent Pools. – Cece Dong - MSFT Jan 12 '17 at 08:14
You right i was looking in a wrong place, but now i checked and i can see that the user that run the agent is in the correct role (Agent Pool Service Acount) any idea what else it can be? – Evya2005 Jan 12 '17 at 08:16

its already domain account and its in the "Build Agent Service Accounts" group and also in "Agent Pool Service Account" role – Evya2005 Jan 12 '17 at 08:23
Go to Task Manager and check whether your build agent service is running. – Cece Dong - MSFT Jan 12 '17 at 08:27
It is running as "vsoagent.apptfs.Agent-APPTFS" – Evya2005 Jan 12 '17 at 08:32
Try to re-deploy a windows agent to see whether the issue persist: https://www.visualstudio.com/en-us/docs/build/admin/agents/v1-windows – Cece Dong - MSFT Jan 12 '17 at 08:37
There is another problem, when i try to download again the agent from the TFS i get an empty zip. do u know why? and how can i get a new agent? – Evya2005 Jan 12 '17 at 08:39
....So you deleted the agent on server? How about just re-run ConfigureAgent.cmd that you have? – Cece Dong - MSFT Jan 12 '17 at 08:53
You may share your configure process here. Also, have you upgraded your TFS 2015 to the latest edition TFS 2015.3? – Cece Dong - MSFT Jan 12 '17 at 09:00
I added my configuration process. and my TFS version is 2015.3 – Evya2005 Jan 12 '17 at 09:19
I couldn't find any issue according to the configuration process or your setting, did this build agent work before? – Cece Dong - MSFT Jan 12 '17 at 09:28
I found the problem tnx. – Evya2005 Jan 12 '17 at 10:13
