Server install doesn't work

[TheInfiniteWin]

I'm trying to run a server for FTB Infinity Evolved 1.7 - 3.1.0. When installing the server I get this error:

2021/05/23 16:41:04 Downloaded 734 successful, 3 failed, 0 incomplete.
Some downloads failed. Would you like to continue anyway? (y/n) [y]

After continuing and trying to run the server I get this error:

"Do you agree to the Mojang EULA available at https://account.mojang.com/documents/minecraft_eula ?"
[y/n]y

Press any key to continue . . .

Any Ideas as to why this happens?

I also tried running both jars and they both result in modded blocks not working.

I had this same issue I found " Currently Azure Functions only support Java 8. "
so I changed to java 8 and it worked. I hope this helps
