ISY Finder - Not Found On Laptop (Travelling) remote desktop to home does find it

[GTCJ]

I am travelling and on Thursday I logged into my system from my laptop.  I changed hotels on Friday and ever since have been unable to access the administrative console.  I have flushed the Java cache and re-installed the deal that shows up on the desktop.  ISY994i is ported out to port 88.  Turning off the firewall and antivirus does not change things.  Have had this happen several times over the years and clearing the Java cache has always restored. 

I am able to remote desktop to a different machine at home and run the console.

What have I missed?

I'm assuming you are using port forwarding rules instead of the portal. Have you verified the external IP address to your home to ensure that the address is correct? It's possible that it may have changed or typed incorrectly

Are you connecting to your directly to your home IP address, thru a DDNS updtated domain, thru the portal, or how?   (there are multiple methods, we need to know which you use).

Is remote desktop using the same method?  or microsoft's portal?

FWIW, I never run the admin console directly while traveling anymore.  If I happen to need the admin console while traveling I use remote desktop and run it on a machine in my house.   I originally developed that plan because I wanted to quit taking my laptop after I upgraded to an iPad pro with keyboard.  (Using Microsoft's remote desktop app on the iPad to phone home).

Hello GTCG,

When you travel, you are not on the local network. What you need to do is to find the remote URL for your ISY, click the Add button, paste the URL.

With kind regards,

Michel

Have done this for years while travelling.  I get to the ISY994i like this:. http://server.domainname.com:88. (domain name not actual)

As I said, it worked fine on Thursday, changed hotel on Friday and no more.  Obviously when accessing via remote desktop, the local 192.168.1.160:88 address is used by the local machine.

After spending way too much time trying to figure this out, I decided to connect the laptop to the Internet using my mobile phone wifi hotspot.  

For some reason, It worked and connected to the ISY994i Administrative Console flawlessly.  The hotel wifi must be configured in a fashion that doesn't like some external connections.

Sorry about the wild goose chase.

Problem solved.

Sometimes certain port ranges are blocked.

I never tried to connect to my AC from outside my home wifi network. Reading these posts, and being abroad for a couple of days, I gave it a try by doing the following :

On my Google Wifi App on my phone I opened the http port of my ISY, 8*** (first DHCP IP Reservations and then Port Forwarding)

In the AC  ISY Finder, I clicked on Add and entered http://myIPaddress:8***

I was not able to make it work. Any ideas what I may be doing wrong ?

Larry is correct. Though it is good practice to use an alternative port and have "security by obscurity", the combination of not working on the hotel wlan but working on you phone's hotspot means that the hotel's network blocks some non-standard ports, like :88.

If you are not using SSL I would really suggest using it and mapping to :443.

and don't forget the 'https' with port 443 if not already using a more secure protocol.
