I am unable to open the Appian 7.4 designer even after successful installation a

What is the status of your Appian engines?
Run: <APPIAN_HOME>/server/_scripts/diagnostic/checkEngine.sh
Are there any errors in <JBOSS_HOME>/standalone/log/server.log?

Hi Tim,

The server.log does not report any errors. I have attached the server log for your reference.

I also ran the checkEngine script. I have attached the diagnostic report for your perusal.

server.log

checkengine.sh

Since the server.log doesn't contain any errors we can assume the checkengine output is also showing all engines as Okay (we cannot confirm since you attached the script itself instead of the output of its execution).

Based on the symptoms it could be an issue with the hosts file of the server or an issue with where you are testing.

1. If you are testing DIRECTLY on the server where you installed Appian then you can definitely use localhost:8080/.../designer

---> This requires you to have an entry in the hosts file C:\\Windows\\System32\\drivers\\etc of type


127.0.0.1 aaaa.bbb.ccc aaaa localhost

for example, if the hostname of the server is eduardo.appiancorp.com then the entry should read

127.0.0.1 eduardo.appiancorp.com eduardo localhost


2. But if you installed Appian on Server A and want to test using a web browser on Machine B then you cannot use localhost since localhost means "this computer". In that case you need to use the server name such as:

myserver.mycompanydomain.com:8080/.../designer

Hi Eduardo,


I am testing directly on the server I have installed the Appian hence using localhost:8080/.../designer.

Hostname of the server is lp-3c970e26ff39 hence I made an entry in the host file
as below

127.0.0.1 lp-3c970e26ff39 localhost.

Even after having the above entry in the host file ( C:\\Windows\\System32\\drivers\\etc)
and restarting my servers I still see " This page can't be displayed' message.

Checkengine output shows okay. The summary is as follows

Does clicking on lp-3c970e26ff39/.../designer work?

No , it did not work. Please find the attached screenshot for reference.

My bad, please try clicking on this one:

lp-3c970e26ff39:8080/.../designer

This link too does not work .. I am getting the same message. Screenshot attached.

What's the result of opening a command prompt and typing:

hostname

and hitting enter? Is this a Windows machine?

On typing hostname in the windows command prompt this is what I get. Yes this is a windows machine.

C:\\>hostname
