Broken Pictures/Icons & Cant upload new ones after changing URL domain

[gcmtnskr]

Describe the bug

Missing Profile pictures and CANT upload any new profile pictures or change team icon AFTER changing switching domains.

Context

• Hardware: *Linode
• YunoHost version: LATEST
• I have access to my server: Through SSH | through the webadmin |
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: no

Steps to reproduce

• If the error occurs in your browser, explain what you did:
  1. Go to 'YunoHost admin web panel
  2. Click on 'applications''
  3. Clock on 'MatterMost'
  4. Change the access URL of this application (domain and/or path)
  5. *Change your domain"
  6. Go to new mattermost URL
  7. *Broken profile pictures and unable to upload new profile pictures or team icons"
  8. NOT all pictures are broken, but mostly 80%
  9. Switching back to original domain "fixes" it and all is normal

Expected behavior

A mattermost that works
ALSO!!!!!!!!!!! - guess what... CALLS dont work on my original domain path. example.com/forum..
When switching to forum.example.com, they work. When switching back to the subdirectory URL, CALLS dont work. (another bug itsself worth mentioning here)... And yes i enable them.
