I have been trying to deploy a simple web app to our website for the last two days, but have not been able to get it to load. I have gone through the process several times, but I must be missing something. The web app (http://www.webapptestbed3.epd-pgh.com/) displays the loading bars for a bit and then times out.
Here is what I have done so far:
1. Installed Web App Builder 2.8
2. Registered web App Builder
3. Opened Web App Builder and created a simple web app that points to a map and data on our ArcGIS Online account that is all shared publicly. The Web App successfully launches from within Web App Builder.
4. Downloaded the Web App as a zip file from Web App Builder, unzipped it, and deployed it to a test domain using an FTP: http://www.webapptestbed3.epd-pgh.com/
Set up a Proxy following these directions: https://community.esri.com/groups/technical-support/blog/2015/04/07/setting-up-a-proxy
This is the code for my proxy.config file, I’m using the ClientId and ClientSecret from my registered Web App Builder 2.8:
<?xml version="1.0" encoding="utf-8" ?>
<ProxyConfig allowedReferers="*"
mustMatch="true">
<serverUrls>
<serverUrl url="http://services.arcgisonline.com"
matchAll="true"/>
<serverUrl url="http://http://pc31.epd-pgh.office"
matchAll="true"/>
<serverUrl url="https://epd-pgh.maps.arcgis.com"
clientId="…"
clientSecret="…"
oauth2Endpoint="https://epd-pgh.maps.arcgis.com/sharing/oauth2"
matchAll="true"/>
</serverUrls>
</ProxyConfig>
5. To test the proxy, per the readme file, I entered http://pc31.epd-pgh.office/DotNet/proxy.ashx?ping into my browser and received this response:
{ "Proxy Version": "1.1.2", "Configuration File": "OK", "Log File": "Not Exist/Readable"}
6. Then I tested if I could access a service through the proxy by entering http://services.arcgisonline.com/ArcGIS/rest/services/?f=pjson into my browser. The json displayed in my browser.
7. Next I opened the config.json file for the Web App I had downloaded and updated the poxy URL:
"wabVersion": "2.8",
"isTemplateApp": true,
"isWebTier": false,
"httpProxy": {
"useProxy": true,
"alwaysUseProxy": false,
"url": "http://pc31.epd-pgh.office/DotNet/proxy.ashx",
"rules": []
},
8. Then I added the App following these instructions: http://doc.arcgis.com/en/arcgis-online/manage-data/add-items.htm
I wasn’t sure whether the data source should be https://pc31.epd-pgh.office:3344/webappbuilder/apps/6/ or http://www.webapptestbed3.epd-pgh.com/ so I tried both. I registered each and received an AppId for each.
9. I tried adding each AppId in the config.json file, saving, and replacing via the FTP, but neither worked.
I am still only getting the loading screen when I go to http://www.webapptestbed3.epd-pgh.com/. I feel like I have followed all the instructions perfectly – and I know the Web App Builder install and proxy are working correctly. What am I doing wrong?
