PI Manual Logger Web troubleshooting

Problem

When you start the web application and you receive errors such as DNS could not find the server and “Webpage not available”, or website-unavailable is displayed, what’s wrong?

Resolution

Try entering the IP address for the server rather than the server name.

Problem

My Apple device is not connecting to the PI ML Web application and prompts several times for my credentials and appears to be hung. What’s wrong?

Resolution

See the Prompting for credentials multiple times in Safari on iOS devices section.

Problem

My web browser just shows PI Manual Logger title, Tours menu item, OSI logo, and a red pop dialog that says “Could not retrieve data.” What’s wrong?

Resolution

• Verify that your Windows log on account has read/write access to the PI Manual Logger database, as well as execute permissions on all the stored procedures in the database.

• Verify the Web.config file was configured for the correct database.

• Verify Kerberos Delegation is enabled for double-hop scenarios.

Problem

My web browser just shows PI Manual Logger title, Tours menu item, OSI logo, but no error message. What’s wrong?

Resolution

• If you are running Internet Explorer, verify you are not running in compatibility mode.

• Verify JavaScript is enabled in your browser.

• Verify that PI Manual Logger group and user security permissions are configured correctly in PI Manual Logger User Management when tour authorization is configured.

Problem

When I start up the Web application, the Data Entry page is displayed with no data, with “#1 of 0 (NaN remaining)” in the upper right section of the gray area, and with “Limits violated:” in red. What is wrong?

Resolution

Clear the browser cache and enter the main URL http://webServer/PIML.Web in the browser’s Address field where the webServer is the name of the server hosting the PI Manual Logger Web. For more information on how to clear the cache for a specific browser, see How to clear browser cache when using PI Manual Logger Web.

Problem

After I enter my network credentials, I receive the following error:

Google Chrome:

“This webpage is not available”, and clicking More displays the Error code: ERR_ACCESS_DENIED.

Internet Explorer (after attempting multiple logons and just canceling the logon dialog):

401 – Unauthorized: Access is denied due to invalid credentials.

Resolution

• Verify the correct network credentials are being entered.

• Verify the network user is in the IIS_IUSRS security group on the Web/Application Server.

• You may have to clear the browser cache and stored passwords and restart the browser.

Problem

On the Data Entry page, I do not see the Previous value below the Value field or any Historical values.

Resolution

You do not have appropriate access to the SQL Server stored procedures in the database. See Manual installation of SQL Server stored procedures.

Problem

Values are not being sent to PI Data Archive. What’s wrong?

Resolution

Verify PI tags are configured with Windows Security. See PI Data Archive security, as well as the

PI Data Archive 3.4.390 Security Configuration Guide

.

Note: Messages concerning this issue may also appear in the PI Manual Logger Message Log.

Problem

I enabled authorizing tours using the BypassAuth application setting in IIS but still see no tours. What’s wrong?

Resolution

Verify the Windows security users are configured correctly. See Tour authorization for Windows user accounts.

Additionally, select on the home page to re-download tours to the local storage.

The PIML Web IIS web site defaults to connecting to the database as NETWORK SERVICE. If you want individual Windows accounts connecting to the database, verify you have ASP.NET Impersonation enabled for the PIML Web IIS web site. If the SQL Server instance is on a different server than the IIS host machine, Kerberos Delegation will need to be enabled. Refer to the

PI Data Archive 3.4.390 Security Configuration Guide

.

Problem

All users can see every tour even though they are not authorized. What’s wrong?

Resolution

Verify the security is configured correctly in IIS and in PI Manual Logger PC for the permission groups. See Tour authorization for Windows user accounts.

Problem

I am receiving the following error message when I attempt to open the web application in my browser. What’s wrong?
