Recently, I installed the October 2017 cumulative update in SharePoint 2016 on-premises farm. But after completing the patching process successfully, Central Administration site is inaccessible and gives the error "This page can't be displayed" when opened on Distributed Cache server in the farm. On other servers in the farm, Central Administration can be easily accessed. I checked the services that needs to be up and running and everything seems to be fine. Please suggest.
To narrow down this issue, check the following:
Run the Products Configuration Wizard in this server and check again.
Check the network settings, make sure the server can ping the SharePoint Server.
Check if other SharePoint sites can open in this server.
Use another browser to open the CA site.
Check the ULS log to find more error message.
