> The image https://course.soundshine.com.tw/shared_img/256/256F15651848520587.png gets a 200 status from alibabacloud. > Maybe the rewrited image https://course.soundshine.com.tw/shared_img/256/256F15651848520587.png.pagespeed.ce.06-1T8jikK.png is requested to alibabacloud and it don“t have it? The original img url https://doctrans-tw.oss-cn-shenzhen.aliyuncs.com/256/256F15651848520587.png is ali cloud storage url. So rewrite url https://course.soundshine.com.tw/shared_img/256/256F15651848520587.png still from ali cloud seems no issue. But 404 url is https://course.soundshine.com.tw/shared_img/256/256F15651848520587.png.pagespeed.ce.06-1T8jikK.png . It looks pagespeed rewrite not only url but also the img itself. Of course ali cloud will not have this img. I assume this rewrited img should be in pagespeed cache but not. So cause 404. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
