Trying to sign into http://127.0.0.1:8282/signin gives me “Successfully logged out” popup. Won’t let me access dashboard/signin etc. Adding -O or -t to target doesn’t work either.
I think it’s working now? One of the JP nodes died so I swapped both of them and it let me sign into http://127.0.0.1:8282/. Yay!
Weird… though not sure what magic happens. 
However if you encounter this issue again, please try to change your password to a simple one. Sometimes it causes a problem.
I believe it was that. Mudfish seems really good so far. Thank you!
