webcallserver not working

[hyuk]

./webcallserver start doesn't work. When can this error occur? For reference, it seems to have stopped working after adding the stream module to nginx, but I don't know the exact cause. The problem persists even after stopping the nginx process. Also, in setenv.sh, I added export JAVA_HOME=/usr/local/java
export PATH=$JAVA_HOME/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/bin
export _EXECJAVA=$JAVA_HOME/bin/java
Before adding this, the Java executable path wasn't found.
Could the problem be caused by the Java file?

FlashphonerWebCallServer-5.3.126

When I run sudo ./webcallserver set-root-mode enable , the error disappears.
The server was working fine a week ago, so why is this suddenly happening?
For reference, it is said that some security measures have been taken on the server in the meantime, but it does not seem that there have been any major changes.

And when I run systemctl start webcallserver , it still doesn't work. The ports aren't listening.

How can I get this command to work?

Good day.
1. Please make sure JDK 21 is installed on the server

java -version

If not, please install
2. Uninstall WCS:

/usr/local/FlashphonerWebCallServer/bin/uninstall.sh

3. Install the latest build 5.3.154
4. If the problem persists, please provide SSH access to the server using this form.
