Distributed Cache cacheHostInfo is null

There are several blog posts on this across the web, many will fix your issue, however, you may find that in some cases, none of them work for you. One such issue is if the configuration file of the Dist Cache has your machine registered, yet it cannot any details about that machine in SharePoint, you will get this error.  Even if you run all those wonderful SharePoint cmdlets.  The fix is to export the configuration file, remove the offending server, then upload the configuration file.  Then your SharePoint cmdlets will work:

1. Export-CacheClusterConfig c: empfile.txt
2. Remove the offending server
3. Import-CacheClusterConfig c: empfile.txt
4. Run the appropriate cmds to add it back

Here is all the scripts I have compiled that will help you to solve any issue you may come across:
