Server won't start

One day, I was playing on my server with one of my friends and I had to stop and restart my server to turn off command blocks. After I had turned my server back on, my friend is able to rejoin but I cannot. I tried restarting my server, turning it off and on again and even tried restarting my computer, but it still doesn't seem to let me in. Whenever I try to join, it loads and then shows me text saying "java.net.ConnectionException: Connection timed out: no further information: . Any way I could stop this from happening?

first I don't think this is the full log can you share the log when the server is offline

Because there is no errors in this log and there is no stopping occurred in this log

I changed the ip name of the server and it started working again, I don't know why but that works, but it doesn't matter anymore. I still appreciate your help though, also the log was from when I was offline.
