Error message "Could not load photos folder" behind httpd reverse proxy 🙁

Error message “Could not load photos folder” behind httpd reverse proxy

The Basics

• Nextcloud Server version (e.g., 29.x.x):
  • 31.0.0.18
• Operating system and version (e.g., Ubuntu 24.04):
  • Rocky Linux 9.5 (Blue Onyx)
• Web server and version (e.g, Apache 2.4.25):
  • “Apache/2.4.62 (Rocky Linux)”
• Reverse proxy and version _(e.g. nginx 1.27.2)
  • “Apache/2.4.62 (Rocky Linux)”
• PHP version (e.g, 8.3):
  • PHP 8.2.27
• Is this the first time you’ve seen this error? (Yes / No):
  • Yes and also via a 2nd setup
• When did this problem seem to first start?
  • After installing the NC works fine, not any-more behind the proxy setup partially
• Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
  • Inside LXC’s
• Are you using CloudfIare, mod_security, or similar? (Yes / No)
  • No, the TLS-endpoint is in the reverse proxy

Summary of the issue you are facing:

Dear Support,

After login to the URI behind the very working reverse proxy setup I see the error message “Could not load photos folder” and can’t view the photos.

Yours nextcloud01,

Steps to replicate it (hint: details matter!):

1. Setup a 2nd nextcloud server
2. The message “Could not load photos folder” keeps appearing with use of the login with a admin and a user account.

It’s a config matter on your RP. Should be easy to fix once you spot it.

e.g. See Nextcloud behind Apache reverse proxy, remote.php becomes remote.phpp

[Cosito]

I have the same problem and I cant read/write to the database…

creat a Table (like calendar) is no Problem … but I cant use the tables…

Did you find a solution?

Yours

[Quu2ieJeiwie]

Dear Support,

The trailing forward slash “/” is removed in my httpd RP config and that resolves the issue

[Quu2ieJeiwie]

Even the following directives are not needed in my setup

        "overwrite.cli.url": "http:\/\/my.tld\/nc",
        "overwritehost": "my.tld",
