CloudBerry Server Edition - The underlying connection was closed Hey all, sorry for not saying this earlier....
I got it working!
I installed a pack of updates(Simplix) for Win7-server2008R2 till 03/2023, and updated .Net Framework to 4.8, I think it was some update from the pack, since windows update had only 2-3 updates available, and/but it always failed to install it.
