Apache reverse proxy : Public links in HTTP instead of HTTPS

[Pafzedog]

Summary

Public links are in HTTP instead of HTTPS

Steps to reproduce

• In System console, enable public links
• Access your instance with secure URL: [https]://my.matter.most/my_team/channels/my_channel
• post a message with an attachment
• click to preview the attachment
• click on “get the public link”

Expected behavior

Public link should be : [https]://my.public.link

Observed behavior

public link is : [http]://my.public.link

---

• Which version of Mattermost are you using : 5.21
• A link to documentation used : https://docs.mattermost.com/install/install-debian.html
• What variations have you made that differ from the instructions? : reverse proxy is made with Apache on a dedicated linux box to get TLS with mattermost, here is the unofficial documentation : https://docs.mattermost.com/install/config-proxy-apache2.html

Hi @Pafzedog,
what do you have your site URL set to?

[Pafzedog]

hi !

my site URL is set to [https]://my_reverse.host.name

everything I try for now is working great, desktop clients, webui, Android client with push notifications.
just the public link is created without TLS .

I don’t know but perhaps it related with this : https://github.com/mattermost/mattermost-server/issues/8739#issuecomment-387451051

Since I configured Mattermost to work with TLS in system console (with crt and key, etc …) , there is no more error with public links, I think it’s is a bug .
