Hi Graham,
I think that the problem is that you are using this URL for accesing Moodle:
http://materdei.icomtekasia.com/
when you site real URL is:
http://m285.icomtekasia.com/moodle/
The previous one is a redirection, you must use the real URL always because the redirection is not correctly handled by the app
We'll take a look to handle this type of redirection, but is something difficult because technically we don't really are aware if the server is doing any redirection.
I tried to access using the latest url and it worked for me
