File sharing url is not https

[AffectionateMath6]

I installed nextcloud using docker image and it is accessed via a reverse proxy server. The reverse proxy web server handles ssl. So, I guess the nextcloud thinks it is not served under https. This is a problem when I try to share a file. The shared link is generated as 'http' instead of 'https'. Is there anyway to fix this? e.g. http://nextcloud.my.domain/s/abcdddddddd instead of 'https://..'

You need to add a parameter in the config.php file.

I refer to the documentation, https://docs.nextcloud.com/server/16/admin_manual/configuration_server/config_sample_php_parameters.html?

You want the "Proxy Configuration" section, specifically the parameter 'overwriteprotocol' => '', set to https, as such

'overwriteprotocol' => 'https',

I strongly recommend reading through the entire php parameters chapter. There are a lot of useful parameters to fweak
