/system/xbin/dnscrypt-proxy: can't execute: Permission denied

Hi all,
I wanted to install DNSCcript-proxy on my phone :
My phone is rooted.
I'm describing my installation, I may have made a mistake :

# from my computer
wget https://github.com/DNSCrypt/dnscrypt-proxy/releases/download/2.0.44/dnscrypt-proxy-android_arm-2.0.44.zip
# unzip an move on the device dnscrypt-proxy-android_arm-2.0.44.zip
adb shell

# once on the device
su
mount -o remount,rw -t ext4 /system
cp /sdcard/dnscrypt-proxy-android/dnscrypt-proxy /system/xbin/
mkdir /data/local/dnscrypt-proxy
cp /sdcard/dnscrypt-proxy-android/dnscrypt-proxy.toml /data/local/dnscrypt-proxy/
chmod +x /data/local/dnscrypt-proxy
mkdir /etc/init.d
chmod +x /etc/init.d
cp /sdcard/dnscrypt-proxy-android/99dnscrypt /etc/init.d/
chmod 755 /etc/init.d/99dnscrypt
chgrp shell /etc/init.d/99dnscrypt
## met le contenu, le script fourni ne contient pas d'erreur !
touch /system/etc/init/init_d.rc
cat > /system/etc/init/init_d.rc << EOF
service init_d /system/bin/sh /system/bin/sysinit
    user root
    group root
    disabled
    oneshot
    seclabel u:r:sudaemon:s0

on property:sys.boot_completed=1 && property:sys.logbootcomplete=1
    start init_d
EOF

Here is the mistake I encounter:

Ordissimo_LeNumero1_Mini:/ # /etc/init.d/99dnscrypt
Starting dnscrypt-proxy
.
.
.
failed to start dnscrypt-proxy
Try running '/etc/init.d/99dnscrypt --debug' or enable logging and check the logs for errors

Debug:

Ordissimo_LeNumero1_Mini:/ # /etc/init.d/99dnscrypt --debug
Attempting to run dnscrypt-proxy in foreground
Starting dnscrypt-proxy
/etc/init.d/99dnscrypt[78]: /system/xbin/dnscrypt-proxy: can't execute: Permission denied

All suggestions are welcome!

Thank you

InviZible runs dnscrypt-proxy on Android, so you might want to try that.

As for serving dnscrypt + doh, take a look at this: https://github.com/jedisct1/encrypted-dns-server

Maybe you need to make the application executable:

chmod +x /system/xbin/dnscrypt-proxy

There is a thread dedicated to running dnscrypt-proxy on Android where you may find more useful information.

Alternatively, as suggested above, you can simply install Invizible Pro.

chmod +x /system/xbin/dnscrypt-proxy

This command solved the issue
