Stratum not connecting to hosted template provider?

I’m trying to learn the Stratum protocol by following the instructions on the Getting Started page.

According to the instructions for simplicity, you can point the SV2 Pool to our hosted Template Provider. However, when I start SV2 Pool, I get several warnings and only print two log lines.

Here’s what I get:

$ cargo run -p pool_sv2

here my pool-config.toml file:

# Template Provider config

# tp_address = "127.0.0.1:8442"
# hosted testnet TP 
tp_address = "89.116.25.191:8442"
# hosted regnet TP 
# tp_address = "75.119.150.111:8442"

# tp_address = "75.119.150.111:8442"

# SRI Pool JN config
listen_jn_address = "127.0.0.1:34264"

i ran nmap I don’t think port 8442 is open on that host, so I think that’s the problem.

$ nmap 89.116.25.191

Are there other hosting template providers? Or is there another way to get familiar with Stratum using a template provider hosted on the testnet?
