About Status 300! = 200 for Android

from app-store install Booned Dolphin app, it can connect
www.meterboxcem.com, the result is ok;

from Google play install Boonex Dolphin app,

it can't connect www.meterboxcem.com,

the error message is "Status 300! = 200".

but can connect demo.boonex.com, is ok.

now, i update to dolphin 7.1:  "www.meterboxcem.com" is 7.0.9   

"www.meterboxcem.com/dolph" is 7.0.1

i don't know how to resolve it.   our hosting is tmdhosting

Yes i have same issue since upgrade mobile appfor android I get the http status error

 your 7.1 site needs the captcha before any testing, no one can join your site to test..

You site send HTTP 300 status code, which means multiple choices redirect - http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html

Mobile App cant't handle 300 status code for now.

Please try to remove such redirect if possible or try to enter direct name of your site address without redirect.

As your explained, now it is over, thank you very much.
