error.

Have you ever heard about it?

I'm crossed that.

That was from PageSpeed conf. I try Shard with HTTPS via CloudFlare.. I have signed RSA cert but you know CloudFlare with curl make huge problem. Anyway

And the real problem is Shard, some (especially .js and webp or jpg) files on the shard link give to me 404.

Code:

pagespeed on;
pagespeed ShardDomain https://realdomain.com https://cdn.shard.ed,https://cdnj.shard.ed,https://cdnja.shard.ed,https://cdnjb.shard.ed;
pagespeed MapRewriteDomain https://realdomain.com https://www.realdomain.com;
