The Bitcoin app works only once, and subsequent attempts result in a DNS resolution error

when using ntptime , everything work fine , and i can launch it multiple time :

best strength = -36, best ssid = Sighq, tz = 506099284 best channel 11, best mac 1a:f6:cf:fd:97:70 铭德美家1-2301 mingde2301 1467951276 NETGEAR Qin32 Gutsmodernraven47 506099284 found SSID we know: Sighq Connecting to WiFi network: Sighq password ######## channel 11 mac ########## Waiting for WIFI connection... waiting 2 seconds for wifi connection WiFi connected!

when using any others app using wifi : i can do it only once ( ex bitcoin app ) :

tzonestr = 506099284 best strength = -35, best ssid = Sighq, tz = 506099284 best channel 11, best mac 1a:f6:cf:fd:97:70 铭德美家1-2301 mingde2301 1467951276 NETGEAR Qin32 Gutsmodernraven47 506099284 found SSID we know: Sighq Connecting to WiFi network: Sighq password ######## channel 11 mac ######### Waiting for WIFI connection...

the next time another time :

Waiting for WIFI connection... [E][WiFiGeneric.cpp:654] hostByName(): DNS Failed for api.coindesk.com WiFi connected! IP address: 192.168.43.239 WiFi connected! IP address: 192.168.43.239

The only way to be able to start any wifi app without having this dns error is to start the ntptime before , look like it reset something that the others app don't ..

No, this is incorrect. The Bitcoin app is the only one that has/causes difficulty. The MQTT app and the new unreleased Weather app have no trouble connecting multiple times to wifi.

I updated appBitcoin() to turn off the wifi when the app is exited. This seems to fix this issue.
