Cannot assign requested address

[Jorman]

Hi, the situation is pretty strange, and I'm not so able to understand why this happens, I'll try to explain what is and when happen the error.
I wrote a little bash script to extract listening port with this command
ACTUAL_QBITTORRENT_PORT=$($QBT_BIN server settings connection --username "$QBITTORRENT_USERNAME" --password "$QBITTORRENT_PASSWORD" --url "http://${QBITTORRENT_HOST}:$QBITTORRENT_PORT" --format json | $JQ_BIN '.ListenPort')
When I run it inside putty shell all works, the same when I use it from command line, but if I call the script from a systemd system I get the "Cannot assign requested address" error.
So this's the output if I launch the script

+ OWRT_UNAME=root
+ OWRT_IP_ADDR=10.0.0.1
+ QBITTORRENT_HOST=localhost
+ QBITTORRENT_USERNAME=admin
+ QBITTORRENT_PASSWORD=adminadmin
+ QBITTORRENT_PORT=8081
+ LOG_ENABLE=0
+ LOG_PATH=/tmp
+ [[ 0 == 1 ]]
+ [[ 0 == 1 ]]
++ command -v qbt
+ QBT_BIN=/usr/bin/qbt
++ command -v ssh
+ SSH_BIN=/usr/bin/ssh
++ command -v jq
+ JQ_BIN=/usr/bin/jq
+ [[ -z /usr/bin/qbt ]]
+ [[ -z /usr/bin/ssh ]]
++ /usr/bin/ssh root@10.0.0.1 'cat /tmp/pia-port-forward'
+ REMOTE_PIA_PORT=46786
+ [[ -n 46786 ]]
++ /usr/bin/qbt server settings connection --username admin --password adminadmin --url http://localhost:8081 --format json
++ /usr/bin/jq .ListenPort
+ ACTUAL_QBITTORRENT_PORT=46786
+ [[ 46786 == 46786 ]]
+ [[ 0 == 1 ]]

And this's the output when I call the script from the systemd

As you can see, the ACTUAL_QBITTORRENT_PORT var is not valid because of "Cannot assign requested address" error

Do you've any idea?

Never mind, I found the problem, was my fault, I used ExecStartPre instead ExecStartPost so qbt was launched before qbittorrent and not after!
So, no worry.
