I ran into a an issue today. When I tried to add a user to a site in my SharePoint 2013 site, I got this error:

Sorry, we’re having trouble reaching the server

A google search gave these two possible solutions:

I know it can almost everything that can cause this error. Here are my two öre :) I found that when I tried to add a user, an ajax call was made. And this was the error:

The Web application at http://10.10.10.151 could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application.

Obviosly, the Alternate Access Mappings. What I needed to do was to add the ip-address to my AAM.

This post is amazing. I realy love it

How were you able to troubleshoot the ajax call? How did you know it was made? I’m getting the same error and would like to determine the call being made.

I’m getting an 404 error for http://extranet/_vti_bin/client.svc/ProcessQuery Any idea what would cause that?

Hi.. I have updated My machine RAM size upto 9 GB still I am facing this issue. pls help me on this same.

Thank you for your reply. I would not recommend to update sharepoint javascript files in the hive.

If you definitely sure that it`s failing due to query timeout try to update peoplepicker`s timeout in client`s js: extensions\15\TEMPLATE\LAYOUTS\clientpeoplepicker.js SPClientPeoplePicker.UserQueryMaxTimeout = 25e3; ##<- this is default 25 sec, change it to 60
