SharePoint 2013 People Picker error: “Sorry, we’re having trouble reaching the server.”

I have had a strange error today in my dev lab environment. First I recognized that I could not select users from the People Picker:

Sorry, we’re having trouble reaching the server.

Second I realized that I was not able to use any function that belongs to WCF web services such as the SharePoint REST API, e.g. at http(s)://<server>/_api/web.

Using Fiddler I found this behavior:

HTTP 404 NOT FOUND on /_vti_bin/client.svc/ProcessQuery

Same for /_vti_bin/client.svc/web which is the same as /_api/web.

Search the web I found some hints regarding this error in SharePoint. But nothing worked.

Than I created a own web service “service1.svc” with a simple method in it and placed it in folder <SP-Hive>\isapi where the virtual folder “_vti_bin” is located on the file system.

Result:  I could not call my own web service too. Same result: NOT FOUND.

Than I search the web for “WCF 404” and found some hints to “HTTP Activation” feature of Windows Server OS. Of course this was activated for .NET 3.5 and .NET 4.5.

So I deactivated the “HTTP Activation” feature of .NET 3.5 and .NET 4.5 and re-enabled one by one (1st .NET 3.5, 2nd .NET 4.5 ) them after deactivation.

After that I did a IISRESET. – Than everything works again as expected. 🙂

  1. Great article. I was having the same issue, but decided to try an IISReset before doing the suggested steps, and that seemed to do the trick!

  2. If you definitely sure that it`s failing due to query timeout try to update peoplepicke`s timeout in client`s js:

    extensions\15\TEMPLATE\LAYOUTS\clientpeoplepicker.js

    SPClientPeoplePicker.UserQueryMaxTimeout = 25e3; ##<- this is default 25 sec, change it to 60

  3. Thanks… I was having a very difficult time figuring out the cause of my problems, and this helped identify that HTTP Activation was not even installed on my server. Once installed, a half dozen issues disappeared!!!

  4. Thanks for the article. This happened to me on one of my site collections but not another (both in same farm). However I tried what M suggested and did the IISRESET, and this solved my problem. Cheers to you both.

  5. Don’t try this on Windows server 2008 R2. I tried it and it blew up my SharePoint 2013 install completely. Hosed IIS and securityservice.

  6. Hi in my case I had the same non-functioning people picker and not being able to run say http:://mydev/_api/lists/getbytitle(‘documents’) on the 4th web app /root sc in my Farm. 401 errors also shown in Fiddler. Just did an IISreset and all is well, Strange eh!

  7. Thanks for posting this, it fixed my problem. The guides I followed didn’t even have me install the HTTP Activation feature. I could have spent a lot of time on this figuring it out on my own, i’m glad I found your post.
