After mySite deletion same error with Main Portal:80

Answer 1

Web.config file of "MySite-Host-8080" having some issue which causing the issue when you trying to add the server.Looks like you made changes in the web.config file and remove/ add some tags.

Now you have two options, if you are not using the MySite-host web app then you can simply delete it and rerun the config wizard on new server.

Or Fix the the issue specified node "system.web / h ttpModules" and re run the config wizard. You can compare the web.config from other web application and add that node.
