An effective way to test socks5 proxy with cURL:

curl -x "socks5://<user>:<pass>@<ip>:<port>" -ipv4 -k -v https://api.my-ip.io/ip.txt

Important is the -ipv4 option to make the name resolving only ask for IPv4 addresses.

We noticed that without -ipv4 there may be errors like this:

curl: (97) Can't complete SOCKS5 connection to google.com. (3)
