This works as expected. Check your ALLOWED_URL_SCHEMES to ensure that the https scheme has not been mistakenly omitted.

Hi @jeremystretch and thanks.

However: It was previously set to *. Now I have

Allowed URL schemes ('http','https','telnet','ssh','vnc')

but still no luck. Still empty refs. This netbox is running behind a HA-proxy. All sorts forwarded-headers are provided, esp.

http-request set-header X-Forwarded-Proto https

What else could I be looking for?

[jeremystretch]

ALLOWED_URL_SCHEMES is used solely for the sanitization of user-submitted hyperlinks; it has nothing to do with how NetBox itself is running. Try removing the config parameter (restoring the default) and restarting NetBox.

Thanks setting it back shows the default is

file, ftp, ftps, http, https, irc, mailto, sftp, ssh, tel, telnet, tftp, vnc, xmpp

so without ('') around it (which I found in the documents but maybe they just very successfully confused me. I was aware of what the parameter was supposed to do. Just that this discussion suggested that it will only work with correct X-Forwarded- headers (which does not make a lot of sense to be but hey....): #6862

It is working now! Thanks!

Link URL: anything. else. https://www.heise.de/

The link URL must be just a URL. No "anything. else. " in front of it.

[jkoopmann]

Ii am not entirely sure whether or not this was meant to be a funny remark dear @candlerb . :-)

I am fully aware that a link URL is without "anything. else." It was meant to be understood as "whatever I put there, it does not work". And @jeremystretch thankfully pointed me to the correct ALLOWED_URL_SCHEMES which was the solution. So everything is solved now as could be seen at the "accepted answer" status above.

[candlerb]

No, it was not meant to be funny. I took it to mean you had put some arbitrary text in front of the URL, like a comment. But I'm glad it's working now.
