Hi Helmi, thank you for your reply. Yes, I agree that this belongs maybe in another topic, but since the trouble started when I was importing, I put it in here first.
regarding your questions, I have self installed discourse on a DO droplet. All worked fine, also have imported already. But I needed to do a total new reimport because I had forgotten to set the smilies paths. Therefore needed to delete everything. But since then the troubles have started.
I have been able to connect to my board once to restore my backup of all my settings (theme etc) before doing the import. Then I had to abort my import because I had made an error in the location of the smilies, so I had to redo all from scratch again. Therefore, delete everything again, and then reimport. (I thought).
But since then I can’t connect to the site anymore. Discourse doctor says all is fine except it cant find the version of my discourse. regarding logs, please let me know the command for that and I can check. Yes, I have waited, and waited, and waited… still no connection.
I am really stumped into where I need to look to solve this one. If you have any ideas, please let me know 
edt: so I found out how to check the logs… and it is full with SSL errors. So I’m trying to reinstall a new certificate now with this Set up HTTPS support with Let's Encrypt - i truly hope this will fix it.
