Some resources from the CDN take minutes to load because, according to Chrome devtools, are "stalled". This happens only on Chrome and only the first time I open the page in an incognito window. This happened since when we enabled HTTP2 on the CDN. Rolling back to HTTP1.1 solved the issue.
These resources are loaded from 3 different domains served from CloudFront. Some resources are loaded as soon as possible, then some others are stalled for more than a minute (in same cases several minutes) while there's nothing else going on in the network tab. Eventually, these other resources are loaded and everything else as well. See screenshots:
Only on Chrome, only over HTTP2 and only after some resources from the same domain are loaded successfully. What can be the issue?
