Tweets are displaying alternatively on my asp.net websites and microsites?

[ved_singhal]

I am getting tweets from my Twitter account and displaying on my three asp.net websites.

The problem is that,

If I am displaying tweets on a single site then it is working fine, each time I am getting tweets correctly.

However

I am using the same Twitter account to display the tweets on my other two micro site which are hosted on sub-domain then tweets are now displaying alternatively means some time it works and some times it return unauthorized access error.

Of course I am using the new version (API v1.1) of Twitter API.

Please suggest me.

Thanks in advance.
