The issue you are facing:
I have been trying everything I can to get rid of the warning:
- You are accessing your instance over a secure connection, however your instance is generating insecure URLs. This most likely means that you are behind a reverse proxy and the overwrite config variables are not set correctly. Please read the documentation page about this
.
But everytime I try something I does not get rid of it.
I can access the website through the domain and use nextcloud I just want to get rid of the warning.
Is this the first time you’ve seen this error? (Y/N): N
Steps to replicate it:
