Icon doesn't display

[eauchat]

Steps to reproduce

1. update nextcloud to 18.0.2 (from version 15)
2. update "External Sites" app
3. log in to nextcloud — the link to the the external site shows, but no icon
4. open "External Sites" admin settings — any icon that is added, shows a broken img

Expected behaviour

The icon should display properly in the topbar's general view.
Adding an icon in the "External sites" admin options should show non broken img sources.
It should be possible to remove added icons using the little trash button.

Actual behaviour

There is no icon in the topbar (but the text of the external site shows when hovering over the button).
All icons in the "External Sites" admin settings show a broken source.
Clicking on the little trash icon to remove a previously uploaded icon doesn't do anything.

I have the same issue after updating from 15.0.14 to 18.0.2
Server returns a 404 for each icon in apps/external/icons, whether the icons were uploaded before or after the update to nextcloud 18.

Same issue on Nextcloud 18.0.2, external sites 3.5.0

Is there an error in your nextcloud.log file about this?

[eauchat]

Where is supposed to be this file? I don't seem to have any file named like this in my server.
The folder /var/log/nextcloud is empty, in my case.

[nickvergessen]

inside your data directory

[eauchat]

inside your data directory

I just tried to add an icon and nothing was being logged in the nextcloud.log file.

[nickvergessen]

I need more infos to reproduce this.

Can you check the browser console (press F12), switch to the network tab and reload the page. Then filter for images and search for external/icons.

[eauchat]

So doing what you asked @nickvergessen, this is what I get:

The icons listed in the page fail to be fetched (404 status).

The url to the icons failing to be fetched look like this:

https://domain.tld/apps/external/icons/external-dark.svg
https://domain.tld/apps/external/icons/earth.svg
...

But I noticed that the external-dark icon seemed to be also asked by another part of the page, and that request succeeds (200 status). The successful request url is: https://domain.tld/apps/external/img/external-dark.svg.
But maybe that's unrelated and those two external-dark icons are totally different files (https://domain.tld/apps/external/img/earth.svg for example gives a 404 if I try to open it in a tab).

If you need any details from the failing requests, I can give them, but most of the headers seem more to give private information about the setup, and I'm not sure they'd be helpful for you.

[nickvergessen]

do the files exist in data/appdata_*****/external/icons/

[eauchat]

do the files exist in data/appdata_*****/external/icons/

Yes, they do.

The issue for me was fixed after I update to nextcloud 20 (external sites 3.7.1) and re-upload the icons files.

Nextcloud Hub II 23.0.7
External sites 3.10.2

I would just like to say I had the same issue and it was related with name of the file.
I tried to a favicon 32x32 with dashes and it did not work. Ex:. favicon-bag-of-cash.png
As soon as I changed that to: favicon_bag_of_cash.png the External Sites Application loaded the image with no further issues.
I hope this helps.

Nextcloud Hub 5 (27.0.1)
External sites 5.2.0

Same problem here (icon does not load, the name is really basic: "jellyfin.svg").
The admin user is not affected (all icons display correctly)
Simple user does not display any icon from "external sites", not even Nextcloud ones (eg. "external.svg").
