Website Page loading sometimes and sometimes not

My website developed with AngulrJS 1.5 with .Net backend. Its working fine in local system. When we upload all files in server, it is sometimes loading all the files and sometimes not. It says error in CSS and JS like "might be temporarily down or it may have moved permanently to a new web address. ERR_CONTENT_DECODING_FAILED". But this error happens sometimes only when we press ctrl + F5. Since, we are new in AngularJS, we don't know where to start and fix. Please help me
