Windows 11 is not listed as supported for EBO 3.1.

First version supporting Windows 11 are the 2022, EBO 4.0 version.

Hi Mikael, It was running on Windows 10 long back and system got updated to Windows 11 some 1+ years back.
Was running perfectly till day before yesterday on Windows 11.

Windows 10 are on the list for EBO 3.1, as long as you are using Pro or Enterprise.

But it is not tested, and therefore not supported, on Windows 11.

EBO 3.1 was released 2019. 

Windows 11 was released in October 2021.

Also, please note that EBO 3.1 is on limited support only, this could be a great moment to think about upgrading to a fully supported version.

If you open up the Building Operation Software Administrator (thats what its called in 6.0, do not have 3.1 installed), are all the port numbers shown in black?

Someone just mentioned that this could have something to do with upgraded browser, guess it is hard to downgrade that one, and keeping it old...

Thank you all. Had to roll back the system to the point before the windows updates that happened few days ago. Now server is up and running. Thank you all again.
