REST directory should be available, but some IP addresses are being blocked. How can I fix?

Question

I have a series of map services in a REST directory which should be available to any IP address.  However, some users report that they are not able to view the content.

In a test, a laptop was used to access the REST directory using one IP address (wifi network).  This IP blocked every attempt.  The same laptop was then used on a different network, and could access everything without problem.  I have tried clearing browsing history, network cache, turning off and on modums and routers etc at the user end without luck.  The server that hosts the REST directory does not block access.

I would be extremely grateful if someone could five some ideas/ advice about why this is happening, and how to fix it?

With thanks,

Mick

Are the users trying to connect to your REST services directory over port 80 (your web adaptor) or port 6080 (no web adaptor)? It's actually fairly common to have port 6080 blocked, since it's no much of a standard port for much else besides Esri ArcGIS Server, as far as I know.

If they are getting blocked on port 6080, then just installing the web adaptor should get you back up in no time.

Hi Mick, Looks like a firewall is blocking your requests when connecting through wifi network. You should touch base with your network guys on this. use below two commands from command line to verify if this is the issue. When connected from your wifi you should not get response for these commands. ping <> telnet <> 80 or telnet <> 6080 (if you are using default port)
