I had not tried the web console after updating to 1801. But when I try to login I get:
“The underlying connection was closed: An unexpected error occurred on a send.”
No errors in eventlog or IIS-logs. The testserver also with windows server 2016 runs fine.
What could be wrong?
If it is an option, I would simply reinstall the Web Console and IIS roles on that machine.
Will probably be faster than troubleshooting the actual issue I think.
Do you get this on both HTTP and HTTPS? Or do you not have a binding configured for HTTP?
