"Could not connect to appstore: cURL error 28"

,

I’ll try to simply explain my issue.

I made a OpenMediaVault to make a NextCloud on an external drive using docker. I don’t know whats wrong, however when I try to use docker logs -f nextcloudpi, I get this:

If I check the website, all I see is:

Please wait…

Can someone help me. I am a beginner, so if I have done something wrong on either the forum or while explaining, please let me know so I know for in the future, and also, I have searched a lot but didn’t find any working results. If I need to do something, please explain how to do it, and I’ll do it.

I dont use OpenMediaVault, most likely related to OMV.

as ncp docker image works fine for me.

Maybe your external drive is not mounted properly?
I d start by reading some omv documentation, check omv forum too.
What commands are you using to run the container?
Can check ncp docker docs basics here
or other omv tagged threads here.
