Hello,

I have a problem with QR code generation.

Installation:

               OS: OracleLinux 8.6

               Postgresql: 14

               Tomcat: 9.0.64

               h-mdm: 5.06.2

               selinux: disabled (for debug)

               firewalld: disabled (for debug)

When I try to generate QR code, the image seems broken: (image is empty)

catalina.out:

2022-07-15 13:22:08 [INFO] com.hmdm.rest.resource.QRCodeResource : Generating QR-code image for configuration key: 6fb9c8dc81483173a0c0e9f8b2e46be1

2022-07-15 13:22:08 [INFO] com.hmdm.rest.resource.QRCodeResource : Digesting the application file: http://mdm.[somedomain].net/files/hmdm-5.04-os.apk

2022-07-15 13:22:08 [ERROR] com.hmdm.rest.resource.QRCodeResource : Unexpected error while generating the QR-code image

java.net.ConnectException: Connection refused (Connection refused)

Any help is greatly appreciated!
