PI Vision Display Utility Can't Connect to PI Vision Server (Internal Server Error)

Question

I am trying to use the PI Vision Display utility on our PI vision server and it can't seem to connect to the PI vision server when I type it in. It results in an Internal Server Error red x. The PI Vision weblink has been working for months, we just haven't had a need to use the PI Vision Display Utility tool until now.

Some potential helpful background, we have a certificate issue on our PI vision weblink. That could be related to the issue.

This is now solved. The way I found this was a bit convoluted, but the web.config file in the PIPC&#92;PIVision&#92;Utility folder had the following string in the authorization section:    <add accessType="Allow" roles="PI Vision Admins" />   When I took a look at the web.config file in the PIPC&#92;PIVision&#92; folder, I found that the string already existed. This would result in a duplicate key issue for the Utility site, since it inherits the parent web config file. All I did was remove the string above from the web.config file in the PIPC&#92;PIVision&#92;Utility folder and save. This instantly resolved the issue.
