I recently beat the Ender Dragon about an hour ago on my survival world which is hosted on Realms. I visually confirmed that I saw a portal spawn after beating the dragon but I decided to go through the main portal back to my spawn. The credits rolled and Realms had disconnected 2 to 3 times during the credits roll. Upon entering back into my save in The End, the Gateway Portal was gone. Is there any way around this besides spawning another dragon or reloading the backup to fight the dragon all over again?
