Thank you for all the hard work you put into this. Got mine set up within the day.
I did have a slight hiccup with step 23 where we had to boot Realmd.exe
I was getting an error upon launch "The code execution cannot proceed because libcrypto-1_1-x64.dll was not found"
I made sure the system path existed for OPENSSL. The solution for me was copying OpenSSL-Win64 from program files over the server folder. Then copying libcrypto-1_1-x64.dll from OpenSSL-Win64/bin to the same directory as Realmd.exe. From there it worked. Oddly, only copying libcrypto-1_1-x64.dll without having the OpenSSL-Win64 directory produced the same error.
