Hey folks,

We recently switched internet up in the office which entailed the web mapping server getting a new DNS. This has broken Portal  Now, this is the page I get.

Main Portal Page

web.vectorgeomatics.com load my test page fine, web.vectorgeomatics.com/portal/home gives me said error. 

If I remote desktop into the server that portal/server is hosted on and I go start > arcgis web adaptor (portal or server) it tries to load the localhost https://localhost/portal/webadaptor and I get the "There is a problem with this website’s security certificate." and If I hit continue it just loads "The webpage cannot be found".

Anyone have any quick ideas that might fix this short of having to reinstall /  re set everything up? Thanks

what do you mean by "new DNS"?

Instead of using the localhost, use the full name of the machine like: "https://mymachine.dom1.dom2.com:7443/arcgis/home" confirm this works first.

Hey Harley,

We recently got a new ISP which involved us receiving a new static IP address...I am not sure what that entailed changing on the back end, but now I can't really load anything.

Loading the mymachiene.dom1.dom2 also didnt work either, "this page can't be displayed'. Services.msc shows both portal and server running.

try the ..:7443/arcgis/adminpanel  and look at the log files.

if this is not working, then look in the portal's log files located here: <arcgisportal site location>\logs\<your machine name>\portal

There should be some errors that make it a little more clear what's going on.

you may need to talk to your network person at some point. 

if you just want to look, in windows, using a command prompt or powershell, and check the network configuration.. "ipconfig /all" will tell you what the machine name is and what ip is and confirm with the network person if it's right.

ipconfig /all

<returns something like>

Did the domain name of the portal change, or simply the DNS server but the original domain name was retained?

DNS server, domain name retained. Had no idea what happened, ended up reinstalling Portal and its normal again. Thanks for the help folks.
