redirect http to https not work

I have server with Debian 9, ISP 3.1.13, apache 2.4.25. There is website s1.sily-natury.pl. LE SSL works for it but after checking "Redirect HTTP to HTTPS" in ISP nothing happens beside added lines in .vhost file:

Code:

                RewriteEngine on
                RewriteCond %{REQUEST_URI} ^/\.well-known/acme-challenge/
                RewriteRule ^ - [END]
        RewriteCond %{HTTPS} off
                RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L,NE]

Does anybody know what could makes this problem?

 

What should happen instead?
Are you sure the redirect does not work? How do you test it does not work?

 

After check "Redirect HTTP to HTTPS" in ISP, code above appear in vhost file related with s1.sily-natury.pl but I still have to write https://s1.sily-natury.pl to get https. If I write just s1.sily-natury.pl I am not redirected to https://s1.sily-natury.pl. I tried on 3 computers and on each used Chrome, Firefox, Edge. This same on any. There is nothing in logs. I could put them.

 

The redirect does work with http://s1.sily-natury.pl:8080
You have made the LE certificate for port 8080 only or the website is only on port 8080. Or something, I do not know how.

 

I did in each browser ctrl+shift+del and deleted all things from beginning. Also tried ctrl+f5 and only f5. On this computer, http://s1.sily-natury.pl:8080 gives bad request due to lack of https. for s1.sily-natury.pl I set block 403. Of course when I do hhttps://s1.sily-natury.pl it is redirect to https://s1.sily-natury.pl:8080/login/, because I have created .htaccess with this kind of redirection. I tried remove it but nothing changes and still http to https does not working. What happens when you try open s1.sily-natury.pl. Will it be redirected to https://s1.sily-natury.pl or https://s1.sily-natury.pl:8080?

 

Here http://s1.sily-natury.pl:8080 redirects to https://s1.sily-natury.pl:8080/login/ . No errors and green padlock.

Now it works, goes to your ISPConfig login page https://s1.sily-natury.pl:8080/login/
That did not work when I wrote my previous post.

 

Hmm, strange thing. I didn't do anything, because I have whole accesses to server on my private PC in home. Does your browser has empty cache?

PS
Do you know what could I check to fix this? I have checked on 5 computers and on each s1.sily-natury.pl didn't redirect to https.

 

Here the same - not redirecting

Bad Request
Your browser sent a request that this server could not understand.
Reason: You're speaking plain HTTP to an SSL-enabled server port.
Instead use the HTTPS scheme to access this URL, please.

I think you followed the tutorial Let's Encrypt and ISPConfig ... review the steps there, maybe did you miss something.

 

In ISP I checked the option "Redirect HTTP to HTTPS". Each time it works and redirect to https after put to browser - in this case - http://s1.sily-natury.pl. Not this time. Manually putting https://s1.sily-natury.pl works perfect.

 

It looks like that this kind of redirect done by ISP not works for subdomains. I added this redirection for main domain and works perfect. You can check (these are on next server, this time with Ubuntu 18.04 LTS) s1.niebianski-lad.pl and niebianski-lad.pl. Both are with redirect to https.

 

Check the vhost file of that domain whether it has one that ended with .err.

 

Thank you for tip! I will check it and give feedback.

EDIT
There is nothing:

Code:

root@s1:/etc/apache2/sites-enabled# ls
000-apps.vhost    000-ispconfig.conf   100-niebianski-lad.pl.vhost
000-default.conf  000-ispconfig.vhost  100-s1.niebianski-lad.pl.vhost
