Hopefully I can describe the problem properly :
Some days ago I installed mastodon on my VPS (using a subdomain: mastodon.rustysoft.de). I did create a user for me and started following some people. Then, after some time, I’ve learned that it’s possible that users can be identified with
firstname.lastname@example.org. So I did the adjustments in the config files and everything seemed to be ok. But now I realized that my profile on some instances still refers to my subdomain (I clicked on a users profile I was following, then looking at the followers of that user looking for my own one). And changes I did to my profile (which I made perhaps after the config adjustments) are not seen. For example I specified a header image in addition to the profile image and changed the display name.
As you can see, there’s no header image:
But others do see it:
Then I tried to un-follow these users and re-follow them. But still I’m listed in their followers-list with my full (sub-)domain and without the changes I did to my profile. But I guess the changes I made to the config files are ok since other users list me correctly (perhaps all people I started to follow after the adjustments).
So, now I’m not sure if this problem is fixable?
