We had to migrate a client to new premises but as we shut down the server it updated (as it does!)
Once moved to the new location we changed the new public IP address on the router and changed the a record for the RWW site - Magic!!!
The only problem was that today the SSTP service wasn't working although traffic on PORT443 was OK
What could be the problem? We messed around for ages uninstalling and re-installing RRAS till we thought hang on what about that update?
KB5003638 (OS Build 14393.4467) was uninstalled and rebooted now the SSTP VPN on WSE works again
