Please check the server address and your internet connection.<\/strong>.\u201c<\/p>\n<p>Before I address my specific issue with the error, you should review the following Citrix articles:<\/p>\n<p><!--more--><\/p>\n<ul>\n<li>Receiver for Android Connects to the Default StoreFront WebUI<br \/><a href=\"http:\/\/support.citrix.com\/article\/CTX216410\">http:\/\/support.citrix.com\/article\/CTX216410<\/a><\/li>\n<li>Android receivers unable to list apps after upgrading the NS firmware to 11.0<br \/><a href=\"http:\/\/support.citrix.com\/article\/CTX206478\">http:\/\/support.citrix.com\/article\/CTX206478<\/a><\/li>\n<\/ul>\n<p>\u00a0<\/p>\n<h3><span class=\"label label-success\">Here is the environment with its key components<\/span><\/h3>\n<ul>\n<li>Citrix NetScaler 11.0<\/li>\n<li>Citrix NetScaler Load Balancing for StoreFront Servers<\/li>\n<li>Citrix StoreFront 3.5<\/li>\n<li>Citrix Receiver for Android<\/li>\n<\/ul>\n<h3><span class=\"label label-success\">Let's take a look at the problem<\/span><\/h3>\n<p>Please note that other devices (iOS) do not encounter this error and function normally. <br \/>First, check the StoreFront event log to see if there are any requests to the authentication service via the loopback address 127.0.0.1. Later, I discovered that this happened after the browser on the Android device was used to start the session. After that, I looked at the Receiver log and found the following: \u201e<strong>Authentication error: Unable to respond to any of these challenges<\/strong>\u201c as a response from StoreFront.<\/p>\n<p>Something is clearly wrong with StoreFront, especially because of the loopback request. Now, you could waste a lot of time trying to \u201edig into\u201c StoreFront or simply perform a fresh installation of the latest StoreFront version 3.7. The latter solved the loopback problem, but Android devices were still unable to connect and continued to receive the same error message.<\/p>\n<p>After further investigation, I discovered that the source of the problem was the persistence setting \u201e<strong>COOKIE NOTICE <\/strong>for load balancing. However, this is the official setting for StoreFront load balancing, as documented by Citrix\u00a0<a href=\"https:\/\/docs.citrix.com\/en-us\/storefront\/3\/integrate-with-netscaler-and-netscaler-gateway\/load-balancing-with-netscaler.html\">https:\/\/docs.citrix.com\/en-us\/storefront\/3\/integrate-with-netscaler-and-netscaler-gateway\/load-balancing-with-netscaler.html<\/a>\u00a0but it is actually problematic with Android devices.<\/p>\n<h3><span class=\"label label-success\">Solution<\/span><\/h3>\n<p>The solution is to set the load balancing persistence to \u201e<strong>SOURCEIP<\/strong>\u201cand on top of that, I also had to handle the <strong>X-FORWARDED-FOR<\/strong> Option set.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1570\" src=\"http:\/\/www.koetzingit.de\/wp-content\/uploads\/2016\/10\/sf_vslb_setting.png\" alt=\"Sf Vslb Setting\" width=\"332\" height=\"136\"  title=\"Citrix Receiver for Android: An error occurred while connecting.
