I am try to configure a webadaptor with my Portal for ArcGIS and I keep getting the error message below. Can anyone tell me why? Particularly because I have done it (WebAdaptor configuration) before and it (the Portal) worked for several months, until last week when it just stopped working. While trying to trouble shoot, I uninstalled the webAdaptor, then reinstalled, that is when i get the error message.
Thanks for responding. I am unable to access the Portal through the URL you specified. Please note that the Portal has been up and running (web adapter and all) since January, with 17 named users already making active use of it since then.
This problem began last week Thursday, when all of sudden I couldn't log in to the Portal any more. Trying to trouble shoot, I thought it might be a problem with the web adapter (since the error I was getting was on a web adapter page). I therefore uninstalled the web adapter then tried to reinstall it and that's where i got stuck. I just get the error message I posted earlier.
Is Portal installed on the same server the web adaptor is installed? If it's not, are you able to access Portal (using the URL above) on the server Portal is installed on?
If you are, there may be some network issues between the web adaptor server and the Portal server.
Portal is installed on the same server the web adaptor is. And before everything went kaput last week, I and my users could access the Portal through this url: https://lamata-gissvr.lamata-ng.com/arcgis/home/signin.html
which takes us to the login page where we input our in-built usernames and passwords.
It looks like you did not specify the port 7443 in your URL to bypass the web adaptor. I would try Sephe suggestion of restarting Portal, then try the following:
Adding to Jake's suggestion,
The Portal can be configured by Web-Adaptor using an Initial Administrator account. Is "gisportal" an Initial Administrator?
