Hey @Warchant - got my regtest env set up. I was able to reproduce the error on /peers right away. I wasn’t getting errors for other things though. Regardless, I thought that first-class support for testnet/regtest should be completed, and now it has. Please check out the latest updates in v1.1.4 and let me know if you’re still having problems here.

[Warchant]

It is okay for now. Thanks.
