We are trying to set up a site with a domain from strato, a SSL security through cloudflare and the site will be hosted by heroku. However, we are encoutering a problem regarding the accessibility for different friends.
I am personally able to access the site with the https after all the configs. However, my friend who lives 5km away is no able to access the site with wifi, but managed to access it with 4g/5g. Sending the link to my friends ± 100km away results in an error by using wifi and 4g/5g.
Therefore, we were wondering what the problem might be and how were are able to solve it.
Attached picture of the DNS setting.
Uploading picture of the site problem is not possible (maximum of 1 image). However, the following is stated: Not Found, The requested URL was not found on this server.
Thanks in advance!
