Aezakmi browser is made on the basis of Chromium, it does not support login and password authorization for socks5. If you want to use this type of proxy, do authorization in socks5 according to your IP without a username and password (done by the provider).
The principle is something like the following: you look at your real IP on whoer.net and tell it to your proxy provider. He, in turn, binds it to the IP proxy and issues it to you. In the proxy settings in Aezakmi, specify the socks5 protocol, enter the IP and the port that your provider gave you.
Important: the proxy will stop working if your native ip changes (for example, restarting the router with a dynamic IP). Also, the proxy checker will show that it is not always working, just ignore this moment.
