After installing free SSL certificate from Control panel on all 3 of my websites, the webpages started to load firstly without backgorund. After reloading, background showed but photos loaded only around 60%. Reloaded again, few more showing…
I didn’t have this problem before installing free SSL certificate from repective control panel (SSL/TLS; configure;Free SSL certificate…)
After disputed with MS for false positive for more than a week, still not solution, I decided to shift to a sub-domain 66ghz.com and installed SSL certificate from Control Panel as well as two other websites under domain epizy.com.
But right after installtion of SSL certificates, all the website are experiencing the loading issue
I checked your site, and I see the issue you’re having.
It’s really interesting you found this difference when using HTTPS. The classof69 page has over twice the number of images of the hksqrenunion page, but the HTTP version works perfectly whereas the HTTPS page has problems.
So it seems that having HTTPS appears to be making pages with a large number of images work poorly.
I did some testing and I think I may have found some things that could be causing this. There is nothing I found that is of any practical use to you, but I’ve sent everything to iFastNet so they try to find a solution.
Hello!
I checked your websites and all of them seem to get a strange error in the console. A 503 “Service Unavailable” error. Which is strange because you are using the images from your own website which is available.
When individually going to these images and opening them in a new tab they load perfectly.
You should try to implement lazy-loading, it should help but this is quite weird. Probably an issue with iFastNet’s servers or something else.
It wasn’t actually a rate limiting issue, but rather a server issue, specifically related to HTTP/2. HTTP/2 is supposed to improve website performance, but what we saw is the exact opposite. And because HTTP/2 only works with HTTPS, that’s why this issue only happens after setting up SSL.
HTTP/2 has been disabled now, which should fix the issue with some images not loading, and also improve website performance. We hope to be able to enable HTTP/2 again later when we know it can actually help with performance.
I checked again using the first link in your topic, and I see the failed requests too. I checked it using the third link before, but the first one has much more images. So I don’t know what was changed to fix the behavior on HTTPS websites, but it only appears to have solved the issue for smaller pages.
