Cannot open certain websites when SOCKS 5 DNS proxy is enabled on Firefox

Question

Using the terminal, I run the following.

ssh admin@1.2.3.4 -i ~/.ssh/admin -N -D 9090

Firefox is configured as follow.

Many websites work just fine, but certain ones fails and the following error is thrown on the terminal.

channel 1: open failed: administratively prohibited: open failed

My research points to a DNS problem as indicated by running tail auth.log on the server.

error: connect_to ipleak.net: unknown host (Temporary failure in name resolution)

How can I fix this issue?

@MichaelHampton Sometimes the answer is so obvious I don’t even consider it! Switched to `1.1.1.1` and the issue is fixed.Thanks for your help. Mind blown that the DNS servers of DigitalOcean are that shitty. — sunknudsen, Jun 23 '20 at 14:34

I have more points than I know what to do with. Feel free to answer it yourself. You did most of the work anyway. — Michael Hampton, Jun 23 '20 at 15:03

Thanks to Michael’s suggestion, I narrowed the issue down to DNS.

Switching from DigitalOcean’s DNS servers to 1.1.1.1 fixed the issue.

$ cat /etc/resolv.conf
nameserver 1.1.1.1
nameserver 1.0.0.1
