"Target service not allowed" for Dell Server manager - localport 1311

Question

I am relatively new to Sophos UTM. We use Dell servers that use Dell Server Manager on port 1311 to give server vitals. Has worked for a while but has stopped on Windows 2012R2 (still working on Windows 2008R2 but I have to use localhost instead of the file server name?). I added the service as TCP/UDP source 1:65535 and destination 1311. If I add the service to Web Protection > filtering options > Misc >Allowed target services I get a "host not found" using the https://fileserver:1311 url. If I don't I get the service not allowed. Previously, I put my internal servers in the filtering options > Exceptions list to skip authentication and thought that was the fix. Not sure what is the right way is but need to be able to access the tool. 
 Best Regards 
 Eric

Hi, Eric, and welcome to the UTM Community! 
 If you're using Standard mode, skipping the Proxy is configured in the browser, so you'll need to adjust your GPO or PAC file. 
 In this case, I will guess that you would want to consider DNS best practice .

 If adding antivirus to the Exception doesn't fix that, then you will need to skip the proxy for this access.
