I’m trying to run proxychains4, everytime I get an error. I type sudo proxychains4 firefox and the output shows the following message:

what can I do? I checked the proxychains4.conf file, reinstalled it, gave all permissions needed and I still got the same error message. Can anyone help me please?

I tried to run proxychains4 but I always got the same error message. I checked all files, reinstalled and nothing changes
