Your console is a thousand lines long and exactly one of them matters. MCPaste gives you a link anyone can open — with the line that broke already circled, the plugins listed, and the whole thing gone when you say.
The jar wants class file 65 (Java 21). This egg runs yolks:java_17, which stops at 61.
Version mismatches, missing dependencies, tick stalls — the usual suspects get pinned to the top with the line number, so nobody has to scroll to find them.
The Pterodactyl addon copies the console straight here and drops the link on your clipboard. Server name, node and image come along for the ride.
An hour, a day, thirty days, or the second someone opens it. Password-protect it and the log stays between you and whoever you sent it to.
