RE: GP Web Client HTTP Error

Hi,

Many thanks for the assistance, I was able to narrow down the source of the error. The error was due to WSUS role being installed on the server. I was able to get beyond the error by following the instructions on this link - https://docs.microsoft.com/en-us/troubleshoot/mem/configmgr/management-points-stop-responding

In Bindings, Host Name should be blank/empty/nothing showing......

Then run IISRESET and test again. Let us know browser error along with Dynamics log information from Event Viewer if still fails.

If this has never worked, you may need to run a Repair of Web Client and/or reinstall completely, as we're not seeing anything to suggest the issue with Web Client but more the environment you're installing it on.

Thanks

RE: GP Web Client HTTP Error

In IIS Manager, click on the site you have Web Client installed on and then click into 'Authentication'. Verify that only Anonymous Authentication shows as enabled.

Under that same site, click on the 'GP' directory and then 'Authentication' again, verify that Anonymous Authentication and Forms Authentication are both enabled. Forms Auth should show 'HTTP 302 Login/Redirect' for the Response Type.

The 'WebManagementConsole' would have 'Anonymous Authentication' and 'Windows Authentication' enabled, with Windows Auth showing 'HTTP 401 Challenge' for the Response Type.

If you make any changes, run an IISRESET and test Web Client again.

As well, click on the IIS site you have Web Client installed and then go into Bindings. For the HTTPS binding, verify the following settings are true/correct:

--Type: https

--IP Address: All Unassigned

--Port: 443

--Host Name: <blank>

--'Require Server Name Indication' option - unmarked

--SSL Certificate >> should be the name of your SSL certificate being used for Web Client.

Again, if you make any changes, run IISRESET and test Web Client again.

Also, when you get that message, what shows in Event Viewer on the server where Web Client is installed, specifically in the 'Dynamics' log?

Has this Web Client ever worked or not at all yet?

Thanks

RE: GP Web Client HTTP Error

Looking at the error message information and the following Web Client troubleshooting blog:

community.dynamics.com/.../common-web-client-issues

For the HTTP Error 500.19, you'll want to check that all IIS pre-requisites are installed, as also mentioned in this same blog.

Once you get everything installed, restart the GP Session Central Service and GP Session Service and attempt to access and login to Web Client again.

Thanks
