Link can't be opened?

Since the beginning of the school year, we have been working partially with Moodle in the school. Most teachers upload the material they have studied in class to this platform

Now the problem is that my bio teacher uploaded a link that I can't access. First I tried to open the link via the app, but unfortunately that didn't work. Then I tried Chrome, the preinstalled browser on my mobile phone and the Adblock browser but none of these apps or browsers could open this link

Now I've tried on my laptop. First on Google Chrome, then on Firefox and finally on Microsoft Edge but it didn't work there either. I can open the main page of the link, but the link itself can't be opened

When I open the link, the message appears that the loading time has been exceeded. All other sites do not work properly only this particular link

Since I do not know whether outsiders are allowed to access this link, I will not include the link

Does anyone maybe have any idea why this particular link is not available?

I get the feeling that the teacher just sent the wrong link…

Otherwise it is up to the server on which this page is located, may be down.

In any case, it shouldn't be due to your devices

Yes, I also think that he used the wrong link. It can't be due to the server because, as already mentioned above, the main page is only available this particular link

Try to open this page and tell me if it is available or not

http://www.ls-bw.de/,Lde/Startseite

Yup, is available from me

After a little experimentation, the link works at once. I just had to remove the https: // and the www

The site doesn't have an Ssl certificate either, probably because of that.
Nice that it works now ^^
