Hi,
We recently made a change to our DNS settings, which coincides with our iphone app breaking. The old DNS settings should still work fine, i.e it should be a seamless switchover.
- In a browser, the site appears
- Over 3G, the server appears unreachable to our app (hard to provide more info, iphone build was outsourced)
- over wifi, the server is reachable fine
- after a hard reset of the phone, over 3G, the server is reachable fine
This inconsistent behaviour (repeated on 2 handsets to verify) is quite puzzling; my best guess is some kind of DNS caching on the handset, that only applies over 3G, and is refreshed after a reset.
Can anyone:
- corroborate such behaviour in the iphone,
- guide as to how I might fix the issue
- or if will fix itself after some kind of cache is cleared, and will this happen automatically, and how frequently?
