Users cannot access webapp

Hello,

Currently there are two users who cannot log onto our webapp. (there are other users which are using the app without a problem)

I have looked into their inspect screen and this is the error they receive:


The message they get is that the website cannot be found and they cannot make a connection.
Do you have an idea what might be the issue?

I am using a custom domain.

I can suggest, that it happen only from some ip addresses. Could you check, please what ip address bind to the domain name (use ping, dig, nslookup tools).
Also, post here the full request in curl form.

ip address:

At the moment i get more and more reports of users not being able to access the webapp. Any idea what can cause this?

Could you please share the URL for which you’re getting the error? (as text, not an image please).

Hi Mark,

The URL which some users cannot access= https://lorio.nl/gv which sends them straight to: https://cvl.lorio.nl/Lorio/index.html

By looking at the sceenshot you posted, the URL seems to be different:

Do you have the full URL that would reproduce the problem?

Regards,
Mark
