With the set-up below, the IRC Server Tunnel, the IRC Client tunnel, and the SOCKS5 IRC tunnel are all on the same I2P router. The IRC client tunnel can find the dest but the SOCKS5 IRC tunnel cannot.

I'm using the SOCKS5 IRC proxy. I've been able to stay connected to my own ircd using the SOCKS tunnel since I started the router a day ago.

I tried to /oper using the wrong password. I was dropped by the ircd. (This is "normal" and happens outside of I2P)

I am not able to reconnect through the SOCKS irc proxy:

I set up a new IRC client tunnel that points to this same dest (wre4majmg2vnbi6id27et7yw6lnpf56wkbm6ftnlwpvxnktq73hq.b32.i2p (aka irc.killyourtv.i2p)), and I'm able to connect.

I'm still unable to connect to my own IRC server using the SOCKS IRC Proxy. Stopping and restarting the SOCKS IRC proxy does not correct the problem. Neither did stopping and starting the IRC server tunnel.

However, I'm currently connected to another IRC server (ilita) using this same SOCKS IRC proxy.

I'll try to leave everything in the current state in case there's anything for me to do or try in order to provide more information.
