"Server Error. Please contact Administrator"

When a customer receives the error Server Error. Please contact Administrator, do the following to troubleshoot the issue.

1. Log in to the customer's Web Admin by going to [site].plexus.cloud.
2. Click Admin and sign in with your credentials.
3. Click Security on the left.
   1. If you see Active Directory Proxy in the Directory service integration dropdown, proceed to step 4. 
   2. If you see None, skip to step 8. 
4. Open SecureLink (https://sl.plexus.tg/rss-servlet/) and click Authenticate with Single Sign-On.
5. Click Customers and find the customer receiving the error.
6. Select the Gatekeeper the customer uses. 
7. From here, you can log in to the machine and restart it or provide the customer with their Local Host Name and Local IP Address to have them restart the machine.
8. If this doesn't resolve the issue, or None was in the Directory service integration dropdown, log in to each app server one at a time and check the application pool and site for that specific customer in IIS (usually already open).
   1. If it is in a stopped state, right-click it and click Start. 
   2. If it is not in a stopped state, contact Jeremy or create a Problem Jira.
