how to properly redirect from http to http2

You don't need to, if your server is configured for http2 and you're using https, then capable browsers will use it.

My server is configured but not redirected to http2  

It’s not a redirection. It’s a different way of sending the data. There are lots of online test services to check the http2 delivery for your site, e.g. https://tools.keycdn.com/http2-test

Negative! www.usenethd.li does not support HTTP/2.0

The support of my server affirms that it has support and the certificate is installed. 

 

It may be cause of ?

.htaccess 

Certificate? Are you sure you are talking about http2 and not https?

yes https

to use the certificate  

Hi @sonimik1

For info, I used the link Opentype kindly provided above to check my server (which has free Lets Encrypt SSL Certificates handled by AutoSSL in WHM) and it confirmed http2 wasn't available too. 

It seems I didn't have the mod_http2 package installed in my current Apache build, so I just added it to the Currently Installed Packages via Easy Apache 4 using the Customize option. It took about 30 seconds so I retested via the checker and now it's green and available, ALPN too.

Not sure if you're on Apache but worth a check in case it's the same problem?

 

@The Old Man, as we figured out he wants to enable https, not http2.

Ah, I no worries! 

I want to redirect to https

 

As i see you already do it 

Yes, but it leaves when I am disconnected and when I connect with user disappears is normal

I asked my hosts about this the other week and was told this, any thoughts?

 

cPanel has implemented http2 support very recently in one of the latest updates however its not compatible with mod_mpm_prefork - This is a module you are currently using as it gives some significant speed improvements vs the other apache MPM. 

There is one warning i notice in the apache documentation on this "Enabling HTTP/2 on your Apache Server has impact on the resource consumption and if you have a busy site, you may need to consider carefully the implications." 

This means your website could have boosts at low users however if your website gets busy your server won't be able to handle as many connections as it currently can. 

When I am disconnected from the web it comes out as it is safe.

but if I connect it comes out as not safe.

there is something I lack but I do not know what it is  

Looks fine to me. I tested the pages accessible to guests and there is a proper forwarding to https. 

But connected does not come out  

It does work for me and probably everyone else accessing the site as guest – I tested it with https://www.whynopadlock.com/.

Are you logged in? Maybe there is additional unsecure stuff showing for your account in that case. 

as a guest if it is safe.

when login is removed

why can it be ?

I told you. There might be additional content shown (like images) which is served over http. I don’t see this content as guest, so I can’t identify it.

And what can I do to solve it?

Open the source code of the page that is generated for you as a logged in user. Search for content (images, CSS, JavaScript …) that is loaded via “http://usenet…” not “https://usenet…”. Find out why they are loaded this way and change it to https. 

They were indeed images. 

It's solved, thank you very much.
