When I open my site first time It shoes HTTP status but when I refresh it it converted into HTTPS. Can you tell me what is the real issue behind this? Here is my website URL; https://itslaptop.com/
Well, I don’t see any HTTPS error (i.e: 500, 520, 527, 525, etc.) can you give me the exact HTTP error code you are receiving?
It could be browser cache. If you try open in incognito mode then your website should be redirected to HTTPS automatically.
