Can't add new translation component

[Tefel]

I installed my own Weblate following the guide: https://docs.weblate.org/en/latest/admin/install/venv-debian.html
I was able to create an account and the project. There is a Server Error when trying to add new component:

Plese check my running Weblate here (if you need credentials let me know)

There are some warnings when starting the server:

I have no idea if warnings are related to the issue. I am using Mysql database, maybe encoding utf-8 plays role here?
What about language? Is it a server fault? I am using webdock VPS server. Please help!

What could be the reason why creating components is not possible? It allows me to navigate to every tab and create new project. Using admin to grant access etc. Seems the website, certificates, Mysql database are working.

Is there anything more in addition to the guide: https://docs.weblate.org/en/latest/admin/install/venv-debian.html
which has to be done, before using the service?

[Tefel]

Is there anything I can do to track the problem? Is it a server, configuration or Weblate issue? I would like to take a consulting hour, obviously, if this can be resolved! Thanks in advance!

The best thing you can do is to avoid spamming it to more locations. This is being discussed at #6559.

This issue looks more like a support question than an issue. We strive to answer these reasonably fast, but purchasing the support subscription is not only more responsible and faster for your business but also makes Weblate stronger.

In case your question is already answered, making a donation is the right way to say thank you!
