Hello, I'm having a trouble with Mudfish on mobile. Whenever I'm connected to my home Wi-Fi, I keep getting MUDEXP_00023 error. I tried changing the password it didn't work, and the error code reference page didn't list my error code either. Please help me figure this out, thank you. 
Weird... Are you under the network firewall? Or personally using the firewall program? Normally "-2" number in the error message means that there's a problem to communicate with the master server of Mudfish for authentication.
