No login screen when accessing from wan, from lan no issues

ℹ️ Support
1

Nextcloud version _: 18.0.4
Operating system and version : Debian 10
nginx: 1.17.10
PHP version _:7.4.5

The issue you are facing:
Loggin in from a local ip to local ip is no problem. Everything works like a charm.
local ip 192.168.1.119 post 443
Loggin in from a local ip to url is a problem.
I see the nextcloud screen and logo. but the login boxes do not apear.
home.sieliakus.nl

Loggin in from local network or outside network i see the same.

URL is with allowed hosts.
nginx servername is home.sieliakus.nl.

i used Install Nextcloud 18 using one script only – Carsten Rieger IT-Services for instalation.

Is this the first time you’ve seen this error?:
Yes, never tried it before.

Steps to replicate it:
goto
home.sieliakus.nl

Very strange issue indeed. I haven’t seen this before. I think we’ll need to see your Nextcloud and nginx configs to troubleshoot.

It’s probably this. That won’t be valid from off-network. Try setting it to your FQDN.

You may need to set other overwrite parameters as well.

Wel everything installed right. but for some reasons the url is not resolving right.
if you use https://sieliakus.no-ip.org you can login. if you use https://home.sieliakus.nl loggin in is not possible??
For sieliakus.no-ip.org i did nothing, only added it to the trusted domains??

i’m lost…
