Hi everyone,

I'm having an immense issues trying to configure my server and portal web adaptors. I'm logging in using the correct admin username and password, my servers are setup properly and I can connect no problem in ArcGIS Manager on each, but for some reason, I keep receiving this error no matter what I do. I've worked through different scenarios but nothing seems to work.

The issue was completely in-house. The web server was moved to a DMZ network and I'm not 100% familiar with our network/firewall rules. Rules had to be set in place to allow traffic between servers. No traffic was allowed, therefore, web adaptor configurations failed immediately. My Enterprise environment is working fine now with no issues.

Sorry, unsure what you meant. The current working configuration is
server.domain.com:portNumber. If portNumber were removed and left as server.domain.com, it would fail.

Also what stage of configuration are you in?

Yes, Federation has been deployed and the system has been running.

When you say configured to the port number, could you dive into that? Also what stage of configuration are you in? If you haven't reached federation, I would unregister the WA from portal via portaladmin then uninstall the WA

Hi @JonEmch , I came cross your comments while trying to troubleshoot the exact same problem titled in this thread on a new server. Leaving that aside. My question is, currently my prod enterprise server's WA was already configured with the port number, but if I remove the port, it would give the the same warning as titled in this thread. Any idea what may have been misconfigured?

My server was recently upgraded from 10.9 to 10.9.1

This could be the culprit. It should've been setup properly with our firewall guy but things slip through the cracks. We're looking into it. Thanks for this suggestion!

Could you work work with your IT/Network team to understand why the admin URL isn't accessible from the Web Server Machine? You might need to allow prerequisite ports through firewall (Ports used by base ArcGIS Enterprise components—ArcGIS Enterprise | Documentation for ArcGIS Enterprise), or whitelist the server/portal URL.

I'm in 10.8.1 and I can confirm the web adaptor, portal and ArcGIS Server are all on 10.8.1. It's a fresh server so it hasn't been used for anything else.

I cannot access https://<myserver>.domain:6443/arcgis/admin from my web server, but I can access it on any other server. Strange..

I'll give it a shot from the command line. Thanks!

What version is your ArcGIS Enterprise?

Could you ensure Web Adaptor is in the same version as GIS Server and Portal, and there is no previous version of Web Adaptor installed on your web server?

Could you access https://gisserver.domain:6443/arcgis/admin from your web server?

Check if you can configure web adaptor from the command line.

JoshClanton

We're still in 10.8.1 so it my not apply, but thanks for the tip and response!

Hey there @JoshuaClanton, for newer versions of ArcGIS Enterprise you only need to enter the machine host, no need to include the port (not sure if you did that in your screenshot but including the port will cause it to fail right quick.)

JoshClanton

Yes, I'm using that URL format along with the 6443 port number and specifying the server domain. The account login is used specifically as the server admin so I don't think that is the issue

The web server is already placed on a DMZ network and has all the necessary security certifications within our organization so that should be good to go. I'm very curious because it fails right away without hardly any load time.

JayantaPoddar

Ensure that you are using the port number while defining the Server URL.

e.g., For the GIS Server URL, are you using "https://<Server.Domain>:6443" ?

Also ensure that you are using credentials of an ArcGIS Server Administrator (e.g. siteadmin).

Allow the required ports through firewall, if not already done.
