HAP+ Error 503: Service Unavailable

[WhizInTraining]

Hi,

 

We're getting this error message when we try to access our HAP, saying that the service is unavailable.

 

I've gone onto the IIS manager on the server, to make sure that it is all up and running, which it is, and I have even restarted it (in the odd event of turning it off and on again).

 

I've looked over the configuration, and nothing has changed since it last previously worked.

 

The error code we get is 503.

 

Any ideas?

 

Thanks

Unfortunately i'm not an expert with IIS but I believe you can usually modify the web.config to show detailed errors:

 

 

Forgive me if you have done this already but I have seen this problem before with HAP but only during new installations so hopefully forcing it to show more detailed error logs may help here.

Hi,

 

Thanks so much for a response.

 

It turns out that in the time waiting for a response, I was actually able to figure it out myself. It had an incorrect application path, but that is all sorted now.

 

Thanks again for responding.

Hi Guys,

 

I'm having the same problem, could you give me some details on how to troubleshoot this please?

 

It was working last week, but got into work this morning and i could not access the HAP login.

 

Any help would be great

 

Thanks,

Manny

Hi Manny,

 

What I did to restore our one, was I went onto the server which it was hosted on, and changed the "Application pool" to "DefaultAppPool" which then got it up and running again.

 

This is of course, assuming that you are getting the exact same error message which I was getting?

 

Before making any changes, make sure that the physical path is correct, and make sure you click "Test settings" (all of this can be found under Basic Settings).

 

Let us know how you get on.

Hi Whizin,

 

The physical path is correct, when I click on "HAP" and test settings we are receiving this error (attached screen shot). Even though no settings have changed (permissions etc).

 

Any suggestions?(here is the screenshot)

 

Cheers,

Hi Manny,

 

I'd say check that your local system account has access to C:\inetpub\wwwroot\HAP.

 

You're getting a different message when you test out your settings to what I had.

 

Are you logged in with an administrator account?

[Manny21555]

Hi Whiz,

 

Yeah the local system account has access to the path. I also gave "Everyone" access to the path as a test but that ended up the same result.

 

And yeh logging on with an administrator account (to the PC it is installed onto yes)

 

Any more suggestions? Very strange that one day it works and the next nothing

 

Cheers,

Manny

Hi Manny,

 

What does it say underneath "Application pool"?

You can ignore that error message, IIS can never accurately check permissions through management console.

 

Just remember to set permissions on the folder that HAP+ is in as per the documentation.

 

 

or run

icacls C:\inetpub\wwwroot\Hap /grant "IIS AppPool\HAP":(RX)

Hi Nick,

 

Is this to help me or Whiz?

 

One morning the HAP was working fine and then the next morning i received the same error as Whiz (well service 503 but sounds like a different fix to me).

 

Should i try what you suggested?

 

Cheers,

Manny

Hi Manny,

 

I think that was suggested for you, As our HAP at my place is working as expected now.

[nickbro]

Sorry it was for Whiz

 

Error 503 isn't much use, if you use a browser on the server you should be able to see the actual error, or check the event logs.

[Manny21555]

No problem,

 

where about should I check the event logs, event viewer on the server, if so which part? Any help would be appreciated. I need it working soon as possible not really sure why it just stopped working. I cannot google a fix so i'm kinda stuck.

 

Cheers,

Manny

Just to note I cannot even ping the address (via name & IP)

Hi Both,

 

I have found the fix, note sure on how anyone else has things setup but here we have a gateway server which needs the service "web application proxy service" to be up and running. The gateway server did not have this running.

 

We have an application server (which is where HAP is installed) and needed ADFS service restarting first then jump back onto the gateway server and restart ADFS service also then start the web application proxy service.

 

After completing all of the above it was working fine

 

I hope this helps someone in the future but its a heads up for you both

 

Cheers,

Nath

Hi Lads,

 

Found a fix, on the server where HAP is installed restart the service ADFS, then for us we have a gateway server which HAP is also configured on, then i restarted ADFS service also. Once I did that i also restarted/started "web application proxy service".

 

Once that is complete HAP now works !

 

Hope that helps someone in the future

 

Cheers,

Manny
