Error reported when integrating NCDownloader into nextcloud

[yzazzx2021]

I am preparing to integrate downloads and online work on nextcloud，I used Debian system as the host，Then an error was reported during the integration download process
aria2 is installed but don't have the right permissions.Please execute command sudo chmod 755 /var/www/html/apps/ncdownloader/lib/Aria2/../../bin/aria2c
The nextcloud that needs to be integrated is run using the Docker container, and Aria2, which serves as the download core, is installed through compilation，I have also used other open-source network disk solutions before and have been able to successfully connect to Aria2 and complete the download using it. The system ctl query also shows active (exited), and the permissions are all 755. I don't know how to handle this,
please help me
