nym-socks5-client 0.9.2 issue with outbound_request_filter.check

[arno01]

my nym-socks5-client 0.9.2 is working only when this check is disabled:

updating the whitelist:

echo "ifconfig.me" | sudo su -s /bin/sh nym -c "tee -a /home/nym/.nym/service-providers/network-requester/allowed.list"

It connects to the client over 127.0.0.1:1977 as expected.

$ sudo su -s /bin/sh nym -c "/home/nym/nym-network-requester"
