Gallery view for image attachments show error symbol

Hi,

when i click on an attachment that is an image, e.g. a jpeg, a black overlay appears, showing a error symbol, i guess that means an error has happened. I tried some things:

save the attachment by clicking on the save symbol: works
copy and past the link url that open the gallery into a new tab: works
look at error logs: nothing conclusive
Inspecting the element in the browser, the console shows an exception:
Uncaught TypeError: _super.prototype.expose_onslide is undefined
expose_onslide https://10.42.0.4/egroupware/api/js/etemplate/etemplate2.min.js?1649420006:250

So my initial conclusion is: there is no problem with the email or the server, as the attachment can be loaded correctly.
There might be a problem with the javascript gallery, as an exception is thrown.

I am using egroupware 21.1.20220408 installed via docker compose as suggested.
Has anyone a pointer where to look next?

Best regards
Sebastian

Hi Sebastian.

I have moved your topic to English.
The EGroupware Mail category is for our email server:

Are you calling EGroupware via this IP address?

And what does this look like in your setup?:

Thanks for your answer.
Yes, when accessing via VPN, i do. Doing DNS over VPN is a tricky thing.
But i tried using a static entry in hosts and call by name. It did not make a difference.

Erwzinge SSL says: ‘By redirecting to https’ in my config
Hostname says: egroupware.subdomain.domain.tld which is the fqdn of the server. The name of the server is ‘egroupware’ and it is resolved correctly.

I tried changing ‘Erwzinge SSL’ to ‘None’ but it did not seem to make a difference. The links URL was still ‘https://’

Best regards
