When you want to run a second Frontend under a Frontend (Virtual Application), it may cause an error when the URL Rewrite rule has the same name in the web config settings of each Frontend. In this case, you can fix the error by changing the URL Rewrite rule name of the internal or external application.
Go to the IIS folder on your computer.
Open the “Web Config” file from the Frontend folder.
Change the Rule Name > React Router Routes name. Thus, it will work when the two names are not the same.
Folder authorization problem:
If IIS was installed later when the server was first installed, access to the “inetpub” folder may be missing.
To fix this, right click on the Frontend and Backend folders.
Properties > Security > IIS > IIS > Users, add the IIS User and grant “Full Control” permission.
Backend 500.30 error:
Connection String related errors:
Navigate to the IIS backend folder on your computer.
Check the “Kuikaappdb and Kuikacommondb” fields from the Appsetting.json file and fix the missing fields.
Server communication problems:
Make sure that your application server has access permissions to your database server.
