It's alive in tor now too: ws://m2swjvhhbxcctnesbwwkqruwlz2fmlbi2u5cyulp7gzzi7pvjj42otqd.onion
That said, since .onion totally allows TLS even via let's encrypt, I will probably put this behind Caddy later and enable HTTPS support. But: It resolved and responded WAY faster! And immediately too, i2p actually needed two tries to get the first connection to work.
Will do the Caddy linkage in a bit; curious to see how it's auto TLS handles onions.
